telegram.ext.filters Module¶

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

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 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.

name¶

Name for this filter. Defaults to the type of filter.

Type: str

data_filter¶

Whether this filter is a data filter. A data filter should return a dict with lists. The dict will be merged with telegram.ext.CallbackContext’s internal dict in most cases (depends on the handler).

Type: bool

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)¶

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)¶

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=None, username=None, allow_empty=False)¶

Bases: telegram.ext.filters.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

Raises

RuntimeError – If chat_id and username are both present.

chat_ids¶

Which chat ID(s) to allow through.

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’.

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").

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)¶

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.

class forwarded_from(chat_id=None, username=None, allow_empty=False)¶

Bases: telegram.ext.filters.Filters._ChatUserBaseFilter

Filters messages to allow only those which are forwarded from the specified chat ID(s) or username(s) based on telegram.Message.forward_from and telegram.Message.forward_from_chat.

New in version 13.5.

Examples

MessageHandler(Filters.forwarded_from(chat_id=1234), callback_method)

Note

When a user has disallowed adding a link to their account while forwarding their messages, this filter will not work since both telegram.Message.forwarded_from and telegram.Message.forwarded_from_chat are None. However, this behaviour is undocumented and might be changed by Telegram.

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/user ID(s) to allow through.

invoice = Filters.invoice¶: Messages that contain telegram.Invoice.

class language(lang)¶

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.

passport_data = Filters.passport_data¶: Messages that contain a telegram.PassportData

photo = Filters.photo¶: Messages that contain telegram.PhotoSize.

Note

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

class regex(pattern)¶

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=None, username=None, allow_empty=False)¶

Bases: telegram.ext.filters.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 to a discussion group 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 to a discussion group 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).

Note

Remember, sender_chat is also set for messages in a channel as the channel itself, so when your bot is an admin in a channel and the linked discussion group, you would receive the message twice (once from inside the channel, once inside the discussion group).

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.

Parameters

chat_id (telegram.utils.types.SLT[int], optional) – Which sender chat chat ID(s) to allow through.
username (telegram.utils.types.SLT[str], optional) – Which sender chat username(s) to allow through. Leading '@' s in usernames will be discarded.
