Utility Functions¶

discord.utils.find(predicate, seq)[исходный код]¶

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.

Параметры:

predicate (Callable[[TypeVar(T)], Any]) – A function that returns a boolean-like result.
seq (Iterable[TypeVar(T)]) – The iterable to search through.

Тип результата:

TypeVar(T) | None

discord.utils.get(iterable, **attrs)[исходный код]¶

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.

Примеры

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')

Параметры:

iterable (Iterable[TypeVar(T)]) – An iterable to search through.
**attrs (Any) – Keyword arguments that denote attributes to search with.

Тип результата:

TypeVar(T) | None

await discord.utils.get_or_fetch(obj, object_type=..., object_id=..., default=..., attr=..., id=...)[исходный код]¶
