class Bot(TelegramObject, AsyncContextManager["Bot"]):
"""This object represents a Telegram Bot.
Instances of this class can be used as asyncio context managers, where
.. code:: python
async with bot:
# code
is roughly equivalent to
.. code:: python
try:
await bot.initialize()
# code
finally:
await bot.shutdown()
.. seealso:: :meth:`__aenter__` and :meth:`__aexit__`.
Note:
* Most bot methods have the argument ``api_kwargs`` which allows passing arbitrary keywords
to the Telegram API. This can be used to access new features of the API before they are
incorporated into PTB. The limitations to this argument are the same as the ones
described in :meth:`do_api_request`.
* Bots should not be serialized since if you for e.g. change the bots token, then your
serialized instance will not reflect that change. Trying to pickle a bot instance will
raise :exc:`pickle.PicklingError`. Trying to deepcopy a bot instance will raise
:exc:`TypeError`.
Examples:
:any:`Raw API Bot <examples.rawapibot>`
.. seealso:: :wiki:`Your First Bot <Extensions---Your-first-Bot>`,
:wiki:`Builder Pattern <Builder-Pattern>`
.. versionadded:: 13.2
Objects of this class are comparable in terms of equality. Two objects of this class are
considered equal, if their :attr:`bot` is equal.
.. versionchanged:: 20.0
* Removed the deprecated methods ``kick_chat_member``, ``kickChatMember``,
``get_chat_members_count`` and ``getChatMembersCount``.
* Removed the deprecated property ``commands``.
* Removed the deprecated ``defaults`` parameter. If you want to use
:class:`telegram.ext.Defaults`, please use the subclass :class:`telegram.ext.ExtBot`
instead.
* Attempting to pickle a bot instance will now raise :exc:`pickle.PicklingError`.
* Attempting to deepcopy a bot instance will now raise :exc:`TypeError`.
* The following are now keyword-only arguments in Bot methods:
``location``, ``filename``, ``venue``, ``contact``,
``{read, write, connect, pool}_timeout``, ``api_kwargs``. Use a named argument for those,
and notice that some positional arguments changed position as a result.
* For uploading files, file paths are now always accepted. If :paramref:`local_mode` is
:obj:`False`, the file contents will be read in binary mode and uploaded. Otherwise,
the file path will be passed in the
`file URI scheme <https://en.wikipedia.org/wiki/File_URI_scheme>`_.
.. versionchanged:: 20.5
Removed deprecated methods ``set_sticker_set_thumb`` and ``setStickerSetThumb``.
Use :meth:`set_sticker_set_thumbnail` and :meth:`setStickerSetThumbnail` instead.
Args:
token (:obj:`str`): Bot's unique authentication token.
base_url (:obj:`str`, optional): Telegram Bot API service URL.
base_file_url (:obj:`str`, optional): Telegram Bot API file URL.
request (:class:`telegram.request.BaseRequest`, optional): Pre initialized
:class:`telegram.request.BaseRequest` instances. Will be used for all bot methods
*except* for :meth:`get_updates`. If not passed, an instance of
:class:`telegram.request.HTTPXRequest` will be used.
get_updates_request (:class:`telegram.request.BaseRequest`, optional): Pre initialized
:class:`telegram.request.BaseRequest` instances. Will be used exclusively for
:meth:`get_updates`. If not passed, an instance of
:class:`telegram.request.HTTPXRequest` will be used.
private_key (:obj:`bytes`, optional): Private key for decryption of telegram passport data.
private_key_password (:obj:`bytes`, optional): Password for above private key.
