"""
This package defines clients as subclasses of others, and then a single
`telethon.client.telegramclient.TelegramClient` which is subclass of them
all to provide the final unified interface while the methods can live in
different subclasses to be more maintainable.
The ABC is `telethon.client.telegrambaseclient.TelegramBaseClient` and the
first implementor is `telethon.client.users.UserMethods`, since calling
requests require them to be resolved first, and that requires accessing
entities (users).

"""
Returns a :ref:`telethon-client` which calls methods behind a takeout session.
It does so by creating a proxy object over the current client through
which making requests will use :tl:`InvokeWithTakeoutRequest` to wrap
them. In other words, returns the current client modified so that
requests are done as a takeout:
Some of the calls made through the takeout session will have lower
flood limits. This is useful if you want to export the data from
conversations or mass-download media, since the rate limits will
be lower. Only some requests will be affected, and you will need
to adjust the `wait_time` of methods like `client.iter_messages
<telethon.client.messages.MessageMethods.iter_messages>`.
By default, all parameters are `None`, and you need to enable those
you plan to use by setting them to either `True` or `False`.
You should ``except errors.TakeoutInitDelayError as e``, since this
exception will raise depending on the condition of the session. You
can then access ``e.seconds`` to know how long you should wait for
before calling the method again.
There's also a `success` property available in the takeout proxy
object, so from the `with` body you can set the boolean result that
will be sent back to Telegram. But if it's left `None` as by
default, then the action is based on the `finalize` parameter. If
it's `True` then the takeout will be finished, and if no exception
occurred during it, then `True` will be considered as a result.
Otherwise, the takeout will not be finished and its ID will be
preserved for future usage as `client.session.takeout_id
<telethon.sessions.abstract.Session.takeout_id>`.
Arguments
finalize (`bool`):
Whether the takeout session should be finalized upon
exit or not.
contacts (`bool`):
Set to `True` if you plan on downloading contacts.
users (`bool`):
Set to `True` if you plan on downloading information
from users and their private conversations with you.
chats (`bool`):
Set to `True` if you plan on downloading information
from small group chats, such as messages and media.
megagroups (`bool`):
Set to `True` if you plan on downloading information
from megagroups (channels), such as messages and media.
channels (`bool`):
Set to `True` if you plan on downloading information
from broadcast channels, such as messages and media.
files (`bool`):
Set to `True` if you plan on downloading media and
you don't only wish to export messages.
max_file_size (`int`):
The maximum file size, in bytes, that you plan
to download for each message with media.

from telethon import errors

async with client.takeout() as takeout:

"""
Starts the client (connects and logs in if necessary).
By default, this method will be interactive (asking for
user input if needed), and will handle 2FA if enabled too.
If the event loop is already running, this method returns a
coroutine that you should await on your own code; otherwise
the loop is ran until said coroutine completes.
Arguments
phone (`str` | `int` | `callable`):
The phone (or callable without arguments to get it)
to which the code will be sent. If a bot-token-like
string is given, it will be used as such instead.
The argument may be a coroutine.
password (`str`, `callable`, optional):
The password for 2 Factor Authentication (2FA).
This is only required if it is enabled in your account.
The argument may be a coroutine.
bot_token (`str`):
Bot Token obtained by `@BotFather <https://t.me/BotFather>`_
to log in as a bot. Cannot be specified with ``phone`` (only
one of either allowed).
force_sms (`bool`, optional):
Whether to force sending the code request as SMS.
This only makes sense when signing in with a `phone`.
code_callback (`callable`, optional):
A callable that will be used to retrieve the Telegram
login code. Defaults to `input()`.
The argument may be a coroutine.
first_name (`str`, optional):
The first name to be used if signing up. This has no
effect if the account already exists and you sign in.
last_name (`str`, optional):
Similar to the first name, but for the last. Optional.
max_attempts (`int`, optional):
How many times the code/password callback should be
retried or switching between signing in and signing up.
Returns
This `TelegramClient`, so initialization
can be chained with ``.start()``.
Example
.. code-block:: python

Iterator over the dialogs (open conversations/subscribed channels).

Arguments
limit (`int` | `None`):
How many dialogs to be retrieved as maximum. Can be set to
`None` to retrieve all dialogs. Note that this may take
whole minutes if you have hundreds of dialogs, as Telegram
will tell the library to slow down through a
``FloodWaitError``.

Whether pinned dialogs should be ignored or not.
When set to `True`, these won't be yielded at all.
ignore_migrated (`bool`, optional):
Whether :tl:`Chat` that have ``migrated_to`` a :tl:`Channel`
should be included or not. By default all the chats in your
dialogs are returned, but setting this to `True` will ignore
(i.e. skip) them in the same way official applications do.

The folder from which the dialogs should be retrieved.
If left unspecified, all dialogs (including those from

If set to ``0``, all dialogs that don't belong to any

By default Telegram assigns the folder ID ``1`` to
archived chats, so you should use that if you need

Creates a `Conversation <telethon.tl.custom.conversation.Conversation>`
with the given entity.
.. note::
This Conversation API has certain shortcomings, such as lacking
persistence, poor interaction with other event handlers, and
overcomplicated usage for anything beyond the simplest case.
If you plan to interact with a bot without handlers, this works
fine, but when running a bot yourself, you may instead prefer
to follow the advice from https://stackoverflow.com/a/62246569/.
This is not the same as just sending a message to create a "dialog"
with them, but rather a way to easily send messages and await for
responses or other reactions. Refer to its documentation for more.
Arguments
entity (`entity`):
The entity with which a new conversation should be opened.
timeout (`int` | `float`, optional):
The default timeout (in seconds) *per action* to be used. You
may also override this timeout on a per-method basis. By
default each action can take up to 60 seconds (the value of
this timeout).
total_timeout (`int` | `float`, optional):
The total timeout (in seconds) to use for the whole
conversation. This takes priority over per-action
timeouts. After these many seconds pass, subsequent
actions will result in ``asyncio.TimeoutError``.
max_messages (`int`, optional):
The maximum amount of messages this conversation will
remember. After these many messages arrive in the
specified chat, subsequent actions will result in
``ValueError``.
exclusive (`bool`, optional):
By default, conversations are exclusive within a single
chat. That means that while a conversation is open in a
chat, you can't open another one in the same chat, unless
you disable this flag.
If you try opening an exclusive conversation for
a chat where it's already open, it will raise
``AlreadyInConversationError``.
replies_are_responses (`bool`, optional):
Whether replies should be treated as responses or not.
If the setting is enabled, calls to `conv.get_response
<telethon.tl.custom.conversation.Conversation.get_response>`
and a subsequent call to `conv.get_reply
<telethon.tl.custom.conversation.Conversation.get_reply>`
will return different messages, otherwise they may return
the same message.
Consider the following scenario with one outgoing message,
1, and two incoming messages, the second one replying::
Hello! <1
2> (reply to 1) Hi!
3> (reply to 1) How are you?
And the following code:
.. code-block:: python
async with client.conversation(chat) as conv:
msg1 = await conv.send_message('Hello!')
msg2 = await conv.get_response()
msg3 = await conv.get_reply()
With the setting enabled, ``msg2`` will be ``'Hi!'`` and
``msg3`` be ``'How are you?'`` since replies are also
responses, and a response was already returned.
With the setting disabled, both ``msg2`` and ``msg3`` will
be ``'Hi!'`` since one is a response and also a reply.
Returns
A `Conversation <telethon.tl.custom.conversation.Conversation>`.
Example
.. code-block:: python
# <you> denotes outgoing messages you sent
# <usr> denotes incoming response messages
with bot.conversation(chat) as conv:
# <you> Hi!
conv.send_message('Hi!')
# <usr> Hello!

class TelegramBaseClient(abc.ABC):
"""
This is the abstract base class for the client. It defines some
basic stuff like connecting, switching data center, etc, and
leaves the `__call__` unimplemented.
Arguments
session (`str` | `telethon.sessions.abstract.Session`, `None`):
The file name of the session file to be used if a string is
given (it may be a full path), or the Session instance to be
used otherwise. If it's `None`, the session will not be saved,
and you should call :meth:`.log_out()` when you're done.
Note that if you pass a string it will be a file in the current
working directory, although you can also pass absolute paths.
The session file contains enough information for you to login
without re-sending the code, so if you have to enter the code
more than once, maybe you're changing the working directory,
renaming or removing the file, or using random names.
api_id (`int` | `str`):
The API ID you obtained from https://my.telegram.org.
api_hash (`str`):
The API hash you obtained from https://my.telegram.org.
connection (`telethon.network.connection.common.Connection`, optional):
The connection instance to be used when creating a new connection
to the servers. It **must** be a type.
Defaults to `telethon.network.connection.tcpfull.ConnectionTcpFull`.
use_ipv6 (`bool`, optional):
Whether to connect to the servers through IPv6 or not.
By default this is `False` as IPv6 support is not
too widespread yet.
proxy (`tuple` | `list` | `dict`, optional):
An iterable consisting of the proxy info. If `connection` is
one of `MTProxy`, then it should contain MTProxy credentials:
``('hostname', port, 'secret')``. Otherwise, it's meant to store
function parameters for PySocks, like ``(type, 'hostname', port)``.
See https://github.com/Anorov/PySocks#usage-1 for more.
local_addr (`str` | `tuple`, optional):
Local host address (and port, optionally) used to bind the socket to locally.
You only need to use this if you have multiple network cards and
want to use a specific one.
timeout (`int` | `float`, optional):
The timeout in seconds to be used when connecting.
This is **not** the timeout to be used when ``await``'ing for
invoked requests, and you should use ``asyncio.wait`` or
``asyncio.wait_for`` for that.
request_retries (`int` | `None`, optional):
How many times a request should be retried. Request are retried
when Telegram is having internal issues (due to either
``errors.ServerError`` or ``errors.RpcCallFailError``),
when there is a ``errors.FloodWaitError`` less than
`flood_sleep_threshold`, or when there's a migrate error.
May take a negative or `None` value for infinite retries, but
this is not recommended, since some requests can always trigger
a call fail (such as searching for messages).
connection_retries (`int` | `None`, optional):
How many times the reconnection should retry, either on the
initial connection or when Telegram disconnects us. May be
set to a negative or `None` value for infinite retries, but
this is not recommended, since the program can get stuck in an
infinite loop.
retry_delay (`int` | `float`, optional):
The delay in seconds to sleep between automatic reconnections.
auto_reconnect (`bool`, optional):
Whether reconnection should be retried `connection_retries`
times automatically if Telegram disconnects us or not.
sequential_updates (`bool`, optional):
By default every incoming update will create a new task, so
you can handle several updates in parallel. Some scripts need
the order in which updates are processed to be sequential, and
this setting allows them to do so.
If set to `True`, incoming updates will be put in a queue
and processed sequentially. This means your event handlers
should *not* perform long-running operations since new
updates are put inside of an unbounded queue.
flood_sleep_threshold (`int` | `float`, optional):
The threshold below which the library should automatically
sleep on flood wait and slow mode wait errors (inclusive). For instance, if a
``FloodWaitError`` for 17s occurs and `flood_sleep_threshold`
is 20s, the library will ``sleep`` automatically. If the error
was for 21s, it would ``raise FloodWaitError`` instead. Values
larger than a day (like ``float('inf')``) will be changed to a day.
raise_last_call_error (`bool`, optional):
When API calls fail in a way that causes Telethon to retry
automatically, should the RPC error of the last attempt be raised
instead of a generic ValueError. This is mostly useful for
detecting when Telegram has internal issues.
device_model (`str`, optional):
"Device model" to be sent when creating the initial connection.
Defaults to 'PC (n)bit' derived from ``platform.uname().machine``, or its direct value if unknown.
system_version (`str`, optional):
"System version" to be sent when creating the initial connection.
Defaults to ``platform.uname().release`` stripped of everything ahead of -.
app_version (`str`, optional):
"App version" to be sent when creating the initial connection.
Defaults to `telethon.version.__version__`.
lang_code (`str`, optional):
"Language code" to be sent when creating the initial connection.
Defaults to ``'en'``.
system_lang_code (`str`, optional):
"System lang code" to be sent when creating the initial connection.
Defaults to `lang_code`.
loop (`asyncio.AbstractEventLoop`, optional):
Asyncio event loop to use. Defaults to `asyncio.get_running_loop()`.
This argument is ignored.
base_logger (`str` | `logging.Logger`, optional):
Base logger name or instance to use.
If a `str` is given, it'll be passed to `logging.getLogger()`. If a
`logging.Logger` is given, it'll be used directly. If something
else or nothing is given, the default logger will be used.
receive_updates (`bool`, optional):
Whether the client will receive updates or not. By default, updates
will be received from Telegram as they occur.
Turning this off means that Telegram will not send updates at all
so event handlers, conversations, and QR login will not work.
However, certain scripts don't need updates, so this will reduce
the amount of bandwidth used.
entity_cache_limit (`int`, optional):
How many users, chats and channels to keep in the in-memory cache
at most. This limit is checked against when processing updates.
When this limit is reached or exceeded, all entities that are not
required for update handling will be flushed to the session file.
Note that this implies that there is a lower bound to the amount
of entities that must be kept in memory.
Setting this limit too low will cause the library to attempt to
flush entities to the session file even if no entities can be
removed from the in-memory cache, which will degrade performance.

Sends message with the given file to the specified entity.
.. note::
If the ``hachoir3`` package (``hachoir`` module) is installed,
it will be used to determine metadata from audio and video files.
If the ``pillow`` package is installed and you are sending a photo,
it will be resized to fit within the maximum dimensions allowed
by Telegram to avoid ``errors.PhotoInvalidDimensionsError``. This
cannot be done if you are sending :tl:`InputFile`, however.
Arguments
entity (`entity`):
Who will receive the file.
file (`str` | `bytes` | `file` | `media`):
The file to send, which can be one of:
* A local file path to an in-disk file. The file name
will be the path's base name.
* A `bytes` byte array with the file's data to send
(for example, by using ``text.encode('utf-8')``).
A default file name will be used.
* A bytes `io.IOBase` stream over the file to send
(for example, by using ``open(file, 'rb')``).
Its ``.name`` property will be used for the file name,
or a default if it doesn't have one.
* An external URL to a file over the internet. This will
send the file as "external" media, and Telegram is the
one that will fetch the media and send it.
* A Bot API-like ``file_id``. You can convert previously
sent media to file IDs for later reusing with
`telethon.utils.pack_bot_file_id`.
* A handle to an existing file (for example, if you sent a
message with media before, you can use its ``message.media``
as a file here).
* A handle to an uploaded file (from `upload_file`).
* A :tl:`InputMedia` instance. For example, if you want to
send a dice use :tl:`InputMediaDice`, or if you want to
send a contact use :tl:`InputMediaContact`.
To send an album, you should provide a list in this parameter.
If a list or similar is provided, the files in it will be
sent as an album in the order in which they appear, sliced
in chunks of 10 if more than 10 are given.
caption (`str`, optional):
Optional caption for the sent media message. When sending an
album, the caption may be a list of strings, which will be
assigned to the files pairwise.
force_document (`bool`, optional):
If left to `False` and the file is a path that ends with
the extension of an image file or a video file, it will be
sent as such. Otherwise always as a document.
file_size (`int`, optional):
The size of the file to be uploaded if it needs to be uploaded,
which will be determined automatically if not specified.
If the file size can't be determined beforehand, the entire
file will be read in-memory to find out how large it is.
clear_draft (`bool`, optional):
Whether the existing draft should be cleared or not.
progress_callback (`callable`, optional):
A callback function accepting two parameters:
``(sent bytes, total)``.
reply_to (`int` | `Message <telethon.tl.custom.message.Message>`):
Same as `reply_to` from `send_message`.
attributes (`list`, optional):
Optional attributes that override the inferred ones, like
:tl:`DocumentAttributeFilename` and so on.
thumb (`str` | `bytes` | `file`, optional):
Optional JPEG thumbnail (for documents). **Telegram will
ignore this parameter** unless you pass a ``.jpg`` file!
The file must also be small in dimensions and in disk size.
Successful thumbnails were files below 20kB and 320x320px.
Width/height and dimensions/size ratios may be important.
For Telegram to accept a thumbnail, you must provide the
dimensions of the underlying media through ``attributes=``
with :tl:`DocumentAttributesVideo` or by installing the
optional ``hachoir`` dependency.
allow_cache (`bool`, optional):
This parameter currently does nothing, but is kept for
backward-compatibility (and it may get its use back in
the future).
parse_mode (`object`, optional):
See the `TelegramClient.parse_mode
<telethon.client.messageparse.MessageParseMethods.parse_mode>`
property for allowed values. Markdown parsing will be used by
default.
formatting_entities (`list`, optional):
A list of message formatting entities. When provided, the ``parse_mode`` is ignored.
voice_note (`bool`, optional):
If `True` the audio will be sent as a voice note.
video_note (`bool`, optional):
If `True` the video will be sent as a video note,
also known as a round video message.
buttons (`list`, `custom.Button <telethon.tl.custom.button.Button>`, :tl:`KeyboardButton`):
The matrix (list of lists), row list or button to be shown
after sending the message. This parameter will only work if
you have signed in as a bot. You can also pass your own
:tl:`ReplyMarkup` here.
silent (`bool`, optional):
Whether the message should notify people with sound or not.
Defaults to `False` (send with a notification sound unless
the person has the chat muted). Set it to `True` to alter
this behaviour.
background (`bool`, optional):
Whether the message should be send in background.
supports_streaming (`bool`, optional):
Whether the sent video supports streaming or not. Note that
Telegram only recognizes as streamable some formats like MP4,
and others like AVI or MKV will not work. You should convert
these to MP4 before sending if you want them to be streamable.
Unsupported formats will result in ``VideoContentTypeError``.
schedule (`hints.DateLike`, optional):
If set, the file won't send immediately, and instead
it will be scheduled to be automatically sent at a later
time.
comment_to (`int` | `Message <telethon.tl.custom.message.Message>`, optional):
Similar to ``reply_to``, but replies in the linked group of a
broadcast channel instead (effectively leaving a "comment to"
the specified message).
This parameter takes precedence over ``reply_to``. If there is
no linked chat, `telethon.errors.sgIdInvalidError` is raised.
ttl (`int`. optional):
The Time-To-Live of the file (also known as "self-destruct timer"
or "self-destructing media"). If set, files can only be viewed for
a short period of time before they disappear from the message
history automatically.
The value must be at least 1 second, and at most 60 seconds,
otherwise Telegram will ignore this parameter.
Not all types of media can be used with this parameter, such
as text documents, which will fail with ``TtlMediaInvalidError``.
nosound_video (`bool`, optional):
Only applicable when sending a video file without an audio
track. If set to ``True``, the video will be displayed in
Telegram as a video. If set to ``False``, Telegram will attempt
to display the video as an animated gif. (It may still display
as a video due to other factors.) The value is ignored if set
on non-video files. This is set to ``True`` for albums, as gifs
cannot be sent in albums.
Returns
The `Message <telethon.tl.custom.message.Message>` (or messages)
containing the sent file, or messages if a list of them was passed.

Uploads a file to Telegram's servers, without sending it.
.. note::
Generally, you want to use `send_file` instead.
This method returns a handle (an instance of :tl:`InputFile` or
:tl:`InputFileBig`, as required) which can be later used before
it expires (they are usable during less than a day).
Uploading a file will simply return a "handle" to the file stored
remotely in the Telegram servers, which can be later used on. This
will **not** upload the file to your own chat or any chat at all.
Arguments
file (`str` | `bytes` | `file`):
The path of the file, byte array, or stream that will be sent.
Note that if a byte array or a stream is given, a filename
or its type won't be inferred, and it will be sent as an
"unnamed application/octet-stream".
part_size_kb (`int`, optional):
Chunk size when uploading files. The larger, the less
requests will be made (up to 512KB maximum).
file_size (`int`, optional):
The size of the file to be uploaded, which will be determined
automatically if not specified.
If the file size can't be determined beforehand, the entire
file will be read in-memory to find out how large it is.
file_name (`str`, optional):
The file name which will be used on the resulting InputFile.
If not specified, the name will be taken from the ``file``
and if this is not a `str`, it will be ``"unnamed"``.
use_cache (`type`, optional):
This parameter currently does nothing, but is kept for
backward-compatibility (and it may get its use back in
the future).
key ('bytes', optional):
In case of an encrypted upload (secret chats) a key is supplied
iv ('bytes', optional):
In case of an encrypted upload (secret chats) an iv is supplied
progress_callback (`callable`, optional):
A callback function accepting two parameters:
``(sent bytes, total)``.
When sending an album, the callback will receive a number
between 0 and the amount of files as the "sent" parameter,
and the amount of files as the "total". Note that the first
parameter will be a floating point number to indicate progress
within a file (e.g. ``2.5`` means it has sent 50% of the third
file, because it's between 2 and 3).
Returns
:tl:`InputFileBig` if the file size is larger than 10MB,
`InputSizedFile <telethon.tl.custom.inputsizedfile.InputSizedFile>`
(subclass of :tl:`InputFile`) otherwise.

Turns the given entity into a valid Telegram :tl:`User`, :tl:`Chat`

Arguments
entity (`str` | `int` | :tl:`Peer` | :tl:`InputPeer`):
If a username is given, **the username will be resolved** making
an API call every time. Resolving usernames is an expensive
operation and will start hitting flood waits around 50 usernames

first `get_input_entity(username) <get_input_entity>` which will

Similar limits apply to invite links, and you should use their

Using phone numbers (from people in your contact list), exact

Unsupported types will raise ``TypeError``.

Turns the given entity into its input entity version.
Most requests use this kind of :tl:`InputPeer`, so this is the most
suitable call to make for those cases. **Generally you should let the
library do its job** and don't worry about getting the input entity
first, but if you're going to use an entity often, consider making the
call:
Arguments
entity (`str` | `int` | :tl:`Peer` | :tl:`InputPeer`):
If a username or invite link is given, **the library will
use the cache**. This means that it's possible to be using
a username that *changed* or an old invite link (this only
happens if an invite link for a small group chat is used
after it was upgraded to a mega-group).
If the username or ID from the invite link is not found in
the cache, it will be fetched. The same rules apply to phone
numbers (``'+34 123456789'``) from people in your contact list.
If an exact name is given, it must be in the cache too. This
is not reliable as different people can share the same name
and which entity is returned is arbitrary, and should be used
only for quick tests.
If a positive integer ID is given, the entity will be searched
in cached users, chats or channels, without making any call.
If a negative integer ID is given, the entity will be searched
exactly as either a chat (prefixed with ``-``) or as a channel
(prefixed with ``-100``).
If a :tl:`Peer` is given, it will be searched exactly in the
cache as either a user, chat or channel.
If the given object can be turned into an input entity directly,
said operation will be done.
Unsupported types will raise ``TypeError``.
If the entity can't be found, ``ValueError`` will be raised.
Returns
:tl:`InputPeerUser`, :tl:`InputPeerChat` or :tl:`InputPeerChannel`
or :tl:`InputPeerSelf` if the parameter is ``'me'`` or ``'self'``.
If you need to get the ID of yourself, you should use
