Utility Functions#

discord.utils.find(predicate, seq)[source]#

A helper to return the first element found in the sequence that meets the predicate. For example:

member = discord.utils.find(lambda m: m.name == 'Mighty', channel.guild.members)

would find the first Member whose name is ‘Mighty’ and return it. If an entry is not found, then None is returned.

This is different from filter() due to the fact it stops the moment it finds a valid entry.

Parameters:
  • predicate (Callable[[T], Any]) – A function that returns a boolean-like result.

  • seq (collections.abc.Iterable) – The iterable to search through.

Return type:

T | None

discord.utils.get(iterable, **attrs)[source]#

A helper that returns the first element in the iterable that meets all the traits passed in attrs. This is an alternative for find().

When multiple attributes are specified, they are checked using logical AND, not logical OR. Meaning they have to meet every attribute passed in and not one of them.

To have a nested attribute search (i.e. search by x.y) then pass in x__y as the keyword argument.

If nothing is found that matches the attributes passed, then None is returned.

Examples

Basic usage:

member = discord.utils.get(message.guild.members, name='Foo')

Multiple attribute matching:

channel = discord.utils.get(guild.voice_channels, name='Foo', bitrate=64000)

Nested attribute matching:

channel = discord.utils.get(client.get_all_channels(), guild__name='Cool', name='general')
Parameters:
  • iterable (Iterable[T]) – An iterable to search through.

  • **attrs (Any) – Keyword arguments that denote attributes to search with.

Return type:

T | None

await discord.utils.get_or_fetch(obj, attr, id, *, default=...)[source]#

This function is a coroutine.

Attempts to get an attribute from the object in cache. If it fails, it will attempt to fetch it. If the fetch also fails, an error will be raised.

Parameters:
  • obj (Any) – The object to use the get or fetch methods in

  • attr (str) – The attribute to get or fetch. Note the object must have both a get_ and fetch_ method for this attribute.

  • id (int) – The ID of the object

  • default (Any) – The default value to return if the object is not found, instead of raising an error.

Returns:

The object found or the default value.

Return type:

Any

Raises:
  • AttributeError – The object is missing a get_ or fetch_ method

  • NotFound – Invalid ID for the object

  • HTTPException – An error occurred fetching the object

  • Forbidden – You do not have permission to fetch the object

Examples

Getting a guild from a guild ID:

guild = await utils.get_or_fetch(client, 'guild', guild_id)

Getting a channel from the guild. If the channel is not found, return None:

channel = await utils.get_or_fetch(guild, 'channel', channel_id, default=None)
discord.utils.oauth_url(client_id, *, permissions=..., guild=..., redirect_uri=..., scopes=..., disable_guild_select=False)[source]#

A helper function that returns the OAuth2 URL for inviting the bot into guilds.

  • permissions (Permissions) – The permissions you’re requesting. If not given then you won’t be requesting any permissions.

  • guild (Snowflake) – The guild to pre-select in the authorization screen, if available.

  • redirect_uri (str) – An optional valid redirect URI.

  • scopes (Iterable[str]) –

    An optional valid list of scopes. Defaults to ('bot',).

    Whether to disallow the user from changing the guild dropdown.

    New in version 2.0.

Returns:

The OAuth2 URL for inviting the bot into guilds.

Return type:

str

discord.utils.remove_markdown(text, *, ignore_links=True)[source]#

A helper function that removes markdown characters.

New in version 1.7.

Note

This function is not markdown aware and may remove meaning from the original text. For example, if the input contains 10 * 5 then it will be converted into 10  5.

Parameters:
  • text (str) – The text to remove markdown from.

  • ignore_links (bool) – Whether to leave links alone when removing markdown. For example, if a URL in the text contains characters such as _ then it will be left alone. Defaults to True.

Returns:

The text with the markdown special characters removed.

Return type:

str

discord.utils.escape_markdown(text, *, as_needed=False, ignore_links=True)[source]#

A helper function that escapes Discord’s markdown.

Parameters:
  • text (str) – The text to escape markdown from.

  • as_needed (bool) – Whether to escape the markdown characters as needed. This means that it does not escape extraneous characters if it’s not necessary, e.g. **hello** is escaped into \*\*hello** instead of \*\*hello\*\*. Note however that this can open you up to some clever syntax abuse. Defaults to False.

  • ignore_links (bool) – Whether to leave links alone when escaping markdown. For example, if a URL in the text contains characters such as _ then it will be left alone. This option is not supported with as_needed. Defaults to True.

Returns:

The text with the markdown special characters escaped with a slash.

Return type:

str

discord.utils.escape_mentions(text)[source]#

discord.utils.utcnow()[source]#

The current aware datetime in UTC.

Return type:

datetime.datetime

discord.utils.snowflake_time(id)[source]#

discord.utils.time_snowflake(dt, high=False)[source]#

Returns a numeric snowflake pretending to be created at the given date.

When using as the lower end of a range, use time_snowflake(high=False) - 1 to be inclusive, high=True to be exclusive.

When using as the higher end of a range, use time_snowflake(high=True) + 1 to be inclusive, high=False to be exclusive

Parameters:
  • dt (datetime.datetime) – A datetime object to convert to a snowflake. If naive, the timezone is assumed to be local time.

  • high (bool) – Whether to set the lower 22 bit to high or low.

Returns:

The snowflake representing the time given.

Return type:

int

discord.utils.generate_snowflake(dt=None)[source]#

Returns a numeric snowflake pretending to be created at the given date but more accurate and random than time_snowflake(). If dt is not passed, it makes one from the current time using utcnow.

Parameters:

dt (datetime.datetime) – A datetime object to convert to a snowflake. If naive, the timezone is assumed to be local time.

Returns:

The snowflake representing the time given.

Return type:

int

discord.utils.basic_autocomplete(values)[source]#

A helper function to make a basic autocomplete for slash commands. This is a pretty standard autocomplete and will return any options that start with the value from the user, case-insensitive. If the values parameter is callable, it will be called with the AutocompleteContext.

This is meant to be passed into the discord.Option.autocomplete attribute.

Parameters:

values (Union[Union[Iterable[OptionChoice], Iterable[str], Iterable[int], Iterable[float]], Callable[[AutocompleteContext], Union[Union[Iterable[str], Iterable[int], Iterable[float]], Awaitable[Union[Iterable[str], Iterable[int], Iterable[float]]]]], Awaitable[Union[Iterable[str], Iterable[int], Iterable[float]]]]) – Possible values for the option. Accepts an iterable of str, a callable (sync or async) that takes a single argument of AutocompleteContext, or a coroutine. Must resolve to an iterable of str.

Returns:

A wrapped callback for the autocomplete.

Return type:

Callable[[AutocompleteContext], Awaitable[Union[Iterable[OptionChoice], Iterable[str], Iterable[int], Iterable[float]]]]

Note

Autocomplete cannot be used for options that have specified choices.

Example

Option(str, "color", autocomplete=basic_autocomplete(("red", "green", "blue")))

# or

async def autocomplete(ctx):
    return "foo", "bar", "baz", ctx.interaction.user.name

Option(str, "name", autocomplete=basic_autocomplete(autocomplete))

New in version 2.0.

discord.utils.filter_params(params, **kwargs)[source]#

A helper function to filter out and replace certain keyword parameters

Parameters:
  • params (Dict[str, Any]) – The initial parameters to filter.

  • **kwargs (Dict[str, Optional[str]]) – Key to value pairs where the key’s contents would be moved to the value, or if the value is None, remove key’s contents (see code example).

Example

>>> params = {"param1": 12, "param2": 13}
>>> filter_params(params, param1="param3", param2=None)
{'param3': 12}
# values of 'param1' is moved to 'param3'
# and values of 'param2' are completely removed.
