telegram.ext.filters Module¶

This module contains the Filters for use with the MessageHandler class.

class telegram.ext.filters.Filters¶

Bases: object

Predefined filters for use as the filter argument of telegram.ext.MessageHandler.

Examples

Use MessageHandler(Filters.video, callback_method) to filter all video messages. Use MessageHandler(Filters.contact, callback_method) for all contacts. etc.

all = Filters.all¶: All Messages.

animation = Filters.animation¶: Messages that contain telegram.Animation.

audio = Filters.audio¶: Messages that contain telegram.Audio.

caption = Filters.caption¶

Messages with a caption. If a list of strings is passed, it filters messages to only allow those whose caption is appearing in the given list.

Examples

MessageHandler(Filters.caption, callback_method)

Parameters:	update (List[`str`] \| Tuple[`str`], optional) – Which captions to allow. Only exact matches are allowed. If not specified, will allow any message with a caption.

class caption_entity(entity_type: str)¶

Bases: telegram.ext.filters.MessageFilter

Filters media messages to only allow those which have a telegram.MessageEntity where their type matches entity_type.

Examples

Example MessageHandler(Filters.caption_entity("hashtag"), callback_method)

Parameters:	entity_type – Caption Entity type to check for. All types can be found as constants in `telegram.MessageEntity`.

class caption_regex(pattern: Union[str, Pattern[AnyStr]])¶

Bases: telegram.ext.filters.MessageFilter

Filters updates by searching for an occurrence of pattern in the message caption.

This filter works similarly to Filters.regex, with the only exception being that it applies to the message caption instead of the text.

Examples

Use MessageHandler(Filters.photo & Filters.caption_regex(r'help'), callback) to capture all photos with caption containing the word ‘help’.

Note

This filter will not work on simple text messages, but only on media with caption.

Parameters:	pattern (`str` \| `Pattern`) – The regex pattern.

class chat(chat_id: Union[int, List[int], Tuple[int, ...]] = None, username: Union[str, List[str], Tuple[str, ...]] = None, allow_empty: bool = False)¶

Bases: telegram.ext.filters._ChatUserBaseFilter

Filters messages to allow only those which are from a specified chat ID or username.

Examples

MessageHandler(Filters.chat(-1234), callback_method)

Warning

chat_ids will give a copy of the saved chat ids as frozenset. This is to ensure thread safety. To add/remove a chat, you should use add_usernames(), add_chat_ids(), remove_usernames() and remove_chat_ids(). Only update the entire set by filter.chat_ids/usernames = new_set, if you are entirely sure that it is not causing race conditions, as this will complete replace the current set of allowed chats.

Parameters:	chat_id (`telegram.utils.types.SLT[int]`, optional) – Which chat ID(s) to allow through. username (`telegram.utils.types.SLT[str]`, optional) – Which username(s) to allow through. Leading ‘@’ s in usernames will be discarded. allow_empty (`bool`, optional) – Whether updates should be processed, if no chat is specified in `chat_ids` and `usernames`. Defaults to `False`

dice = Filters.dice¶

Dice Messages. If an integer or a list of integers is passed, it filters messages to only allow those whose dice value is appearing in the given list.

Examples

To allow any dice message, simply use MessageHandler(Filters.dice, callback_method). To allow only dice with value 6, use MessageHandler(Filters.dice(6), callback_method). To allow only dice with value 5 or 6, use MessageHandler(Filters.dice([5, 6]), callback_method).

Note

Dice messages don’t have text. If you want to filter either text or dice messages, use Filters.text | Filters.dice.

Parameters:	update (`telegram.utils.types.SLT[int]`, optional) – Which values to allow. If not specified, will allow any dice message.

category¶: Filters documents by their category in the mime-type attribute

Note

This Filter only filters by the mime_type of the document, it doesn’t check the validity of the document. The user can manipulate the mime-type of a message and send media with wrong types that don’t fit to this handler.

Example

Filters.document.category('audio/') filters all types of audio sent as file, for example ‘audio/mpeg’ or ‘audio/x-wav’.

Note

This Filter only filters by the mime_type of the document, it doesn’t check the validity of document.

The user can manipulate the mime-type of a message and send media with wrong types that don’t fit to this handler.

Example

Filters.document.mime_type('audio/mpeg') filters all audio in mp3 format.

apk¶: Same as Filters.document.mime_type("application/vnd.android.package-archive").

xml¶: Same as Filters.document.mime_type("application/xml").

zip¶: Same as Filters.document.mime_type("application/zip").

file_extension¶

This filter filters documents by their file ending/extension.

Note

This Filter only filters by the file ending/extension of the document, it doesn’t check the validity of document.
The user can manipulate the file extension of a document and send media with wrong types that don’t fit to this handler.
Case insensitive by default, you may change this with the flag case_sensitive=True.
Extension should be passed without leading dot unless it’s a part of the extension.
Pass None to filter files with no extension, i.e. without a dot in the filename.

Example

Filters.document.file_extension("jpg") filters files with extension ".jpg".
Filters.document.file_extension(".jpg") filters files with extension "..jpg".
Filters.document.file_extension("Dockerfile", case_sensitive=True) filters files with extension ".Dockerfile" minding the case.
Filters.document.file_extension(None) filters files without a dot in the filename.

class entity(entity_type: str)¶

Filters messages to only allow those which have a telegram.MessageEntity where their type matches entity_type.

Examples

Example MessageHandler(Filters.entity("hashtag"), callback_method)

Parameters:	entity_type – Entity type to check for. All types can be found as constants in `telegram.MessageEntity`.

forwarded = Filters.forwarded¶: Messages that are forwarded.

game = Filters.game¶: Messages that contain telegram.Game.

group = Filters.group: Messages sent in a group or a supergroup chat.

Note

DEPRECATED. Use telegram.ext.Filters.chat_type.groups instead.

class language(lang: Union[str, List[str], Tuple[str, ...]])¶

Bases: telegram.ext.filters.MessageFilter

Filters messages to only allow those which are from users with a certain language code.

Note

According to official Telegram API documentation, not every single user has the language_code attribute. Do not count on this filter working on all users.

Examples

MessageHandler(Filters.language("en"), callback_method)

Parameters:	lang (`telegram.utils.types.SLT[str]`) – Which language code(s) to allow through. This will be matched using `.startswith` meaning that ‘en’ will match both ‘en_US’ and ‘en_GB’.

location = Filters.location¶: Messages that contain telegram.Location.

DEPRECATED. Use telegram.ext.Filters.chat_type.private instead.

class regex(pattern: Union[str, Pattern[AnyStr]])¶

Bases: telegram.ext.filters.MessageFilter

Filters updates by searching for an occurrence of pattern in the message text. The re.search() function is used to determine whether an update should be filtered.

Refer to the documentation of the re module for more information.

To get the groups and groupdict matched, see telegram.ext.CallbackContext.matches.

Examples

Use MessageHandler(Filters.regex(r'help'), callback) to capture all messages that contain the word ‘help’. You can also use MessageHandler(Filters.regex(re.compile(r'help', re.IGNORECASE)), callback) if you want your pattern to be case insensitive. This approach is recommended if you need to specify flags on your pattern.

Note

Filters use the same short circuiting logic as python’s and, or and not. This means that for example:

>>> Filters.regex(r'(a?x)') | Filters.regex(r'(b?x)')

With a message.text of x, will only ever return the matches for the first filter, since the second one is never evaluated.

Parameters:	pattern (`str` \| `Pattern`) – The regex pattern.

reply = Filters.reply¶: Messages that are a reply to another message.

class sender_chat(chat_id: Union[int, List[int], Tuple[int, ...]] = None, username: Union[str, List[str], Tuple[str, ...]] = None, allow_empty: bool = False)¶

Bases: telegram.ext.filters._ChatUserBaseFilter

Filters messages to allow only those which are from a specified sender chats chat ID or username.

Examples

To filter for messages forwarded from a channel with ID -1234, use MessageHandler(Filters.sender_chat(-1234), callback_method).
To filter for messages of anonymous admins in a super group with username @anonymous, use MessageHandler(Filters.sender_chat(username='anonymous'), callback_method).
To filter for messages forwarded from any channel, use MessageHandler(Filters.sender_chat.channel, callback_method).
To filter for messages of anonymous admins in any super group, use MessageHandler(Filters.sender_chat.super_group, callback_method).

Warning

chat_ids will return a copy of the saved chat ids as frozenset. This is to ensure thread safety. To add/remove a chat, you should use add_usernames(), add_chat_ids(), remove_usernames() and remove_chat_ids(). Only update the entire set by filter.chat_ids/usernames = new_set, if you are entirely sure that it is not causing race conditions, as this will complete replace the current set of allowed chats.

class telegram.ext.filters.BaseFilter¶

Bases: abc.ABC

Base class for all Filters.

Filters subclassing from this class can combined using bitwise operators:

And:

>>> (Filters.text & Filters.entity(MENTION))

Or:

>>> (Filters.audio | Filters.video)

Exclusive Or:

>>> (Filters.regex('To Be') ^ Filters.regex('Not 2B'))

Not:

>>> ~ Filters.command

Also works with more than two filters:

>>> (Filters.text & (Filters.entity(URL) | Filters.entity(TEXT_LINK)))
>>> Filters.text & (~ Filters.forwarded)

Note

Filters use the same short circuiting logic as python’s and, or and not. This means that for example:

>>> Filters.regex(r'(a?x)') | Filters.regex(r'(b?x)')

With message.text == x, will only ever return the matches for the first filter, since the second one is never evaluated.

If you want to create your own filters create a class inheriting from either MessageFilter or UpdateFilter and implement a :meth:filter method that returns a boolean: True if the message should be handled, False otherwise. Note that the filters work only as class instances, not actual class objects (so remember to initialize your filter classes).

By default the filters name (what will get printed when converted to a string for display) will be the class name. If you want to overwrite this assign a better name to the name class variable.
