filters Module

This module contains filters for use with telegram.ext.MessageHandler, telegram.ext.CommandHandler, or telegram.ext.PrefixHandler.

Changed in version 20.0:

1. Filters are no longer callable, if you’re using a custom filter and are calling an existing filter, then switch to the new syntax: filters.{filter}.check_update(update).

2. Removed the Filters class. The filters are now directly attributes/classes of the filters module.

3. The names of all filters has been updated:

   • Filter classes which are ready for use, e.g Filters.all are now capitalized, e.g filters.ALL.

   • Filters which need to be initialized are now in CamelCase. E.g. filters.User(...).

   • Filters which do both (like Filters.text) are now split as ready-to-use version filters.TEXT and class version filters.Text(...).

class telegram.ext.filters.BaseFilter(name=None, data_filter=False)

Bases: object

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.

Available In

• telegram.ext.CommandHandler.filters

• telegram.ext.MessageHandler.filters

• telegram.ext.PrefixHandler.filters

Added in version 20.0: Added the arguments name and data_filter.

Parameters:

• name (str) – Name for this filter. Defaults to the type of filter.

• data_filter (bool) – 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).

__and__(other)

Defines AND bitwise operator for BaseFilter object. The combined filter accepts an update only if it is accepted by both filters. For example, filters.PHOTO & filters.CAPTION will only accept messages that contain both a photo and a caption.

Returns:

BaseFilter

__or__(other)

Defines OR bitwise operator for BaseFilter object. The combined filter accepts an update only if it is accepted by any of the filters. For example, filters.PHOTO | filters.CAPTION will only accept messages that contain photo or caption or both.

Returns:

BaseFilter

__xor__(other)

Defines XOR bitwise operator for BaseFilter object. The combined filter accepts an update only if it is accepted by any of the filters and not both of them. For example, filters.PHOTO ^ filters.CAPTION will only accept messages that contain photo or caption, not both of them.

Returns:

BaseFilter

__invert__()

Defines NOT bitwise operator for BaseFilter object. The combined filter accepts an update only if it is accepted by any of the filters. For example, ~ filters.PHOTO will only accept messages that do not contain photo.

Returns:

BaseFilter

__repr__()

Gives name for this filter.

Parameters:

update (telegram.Update) – The update to check.

Returns:

True if the update contains one of channel_post, message, edited_channel_post, edited_message, telegram.Update.business_message, telegram.Update.edited_business_message, or False otherwise.

Return type:

bool

class telegram.ext.filters.Caption(strings=None)

Examples

MessageHandler(filters.Caption(['PTB rocks!', 'PTB']), callback_method_2)

See also

telegram.ext.filters.CAPTION

Parameters:

strings (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 telegram.ext.filters.CaptionEntity(entity_type)

Bases: telegram.ext.filters.MessageFilter

class telegram.ext.filters.CaptionRegex(pattern)

Bases: telegram.ext.filters.MessageFilter

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

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

Examples

Use MessageHandler(filters.PHOTO & filters.CaptionRegex(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 | re.Pattern) – The regex pattern.

class telegram.ext.filters.Chat(chat_id=None, username=None, allow_empty=False)

Bases: telegram.ext.filters.MessageFilter

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

Examples

class telegram.ext.filters.Mention(mentions)

Bases: telegram.ext.filters.MessageFilter

Messages containing mentions of specified users or chats.

Examples

MessageHandler(filters.Mention("username"), callback)

class telegram.ext.filters.MessageFilter(name=None, data_filter=False)

Bases: telegram.ext.filters.BaseFilter

Base class for all Message Filters. In contrast to UpdateFilter, the object passed to filter() is telegram.Update.effective_message.

Please see BaseFilter for details on how to create custom filters.

Available In

• telegram.ext.CommandHandler.filters

• telegram.ext.MessageHandler.filters

• telegram.ext.PrefixHandler.filters

Advanced Filters

check_update(update)

Checks if the specified update should be handled by this filter by passing effective_message to filter().

Parameters:

update (telegram.Update) – The update to check.

Returns:

If the update should be handled by this filter, returns True or a dict with lists, in case the filter is a data filter. If the update should not be handled by this filter, False or None.

Return type:

bool | Dict[str, list] | None

abstract filter(message)

This method must be overwritten.

Parameters:

message (telegram.Message) – The message that is tested.

Returns:

dict or bool

class telegram.ext.filters.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 telegram.Message.text of x, will only ever return the matches for the first filter, since the second one is never evaluated.

Types of Handlers

Parameters:

pattern (str | re.Pattern) – The regex pattern.

class telegram.ext.filters.SenderChat(chat_id=None, username=None, allow_empty=False)

Bases: telegram.ext.filters.MessageFilter

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

Examples

• To filter for messages sent to a group by a channel with ID -1234, use MessageHandler(filters.SenderChat(-1234), callback_method).

• To filter for messages of anonymous admins in a super group with username @anonymous, use MessageHandler(filters.SenderChat(username='anonymous'), callback_method).

• To filter for messages sent to a group by any channel, use MessageHandler(filters.SenderChat.CHANNEL, callback_method).

• To filter for messages of anonymous admins in any super group, use MessageHandler(filters.SenderChat.SUPERGROUP, callback_method).

• To filter for messages forwarded to a discussion group from any channel or of anonymous admins in any super group, use MessageHandler(filters.SenderChat.ALL, callback)

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).
