Utility Functions

discord.utils.find(predicate, seq)

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.

参数:

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

• seq (Iterable[TypeVar(T)]) -- The iterable to search through.

返回类型:

TypeVar(T) | None

discord.utils.get(iterable, **attrs)

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.

示例

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')

参数:

• iterable (Iterable[TypeVar(T)]) -- An iterable to search through.

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

返回类型:

TypeVar(T) | None

await discord.utils.get_or_fetch(obj, object_type=..., object_id=..., default=..., attr=..., id=...)

Shortcut method to get data from an object either by returning the cached version, or if it does not exist, attempting to fetch it from the API.

参数:

• obj (Guild | Client) -- The object to operate on.

• object_type (type[TypeVar(_FETCHABLE, bound= VoiceChannel | TextChannel | ForumChannel | StageChannel | CategoryChannel | Thread | Member | User | Guild | Role | GuildEmoji | AppEmoji)]) -- Type of object to fetch or get.

• object_id (int | None) -- ID of object to get.

• default (TypeVar(_D)) -- The value to return instead of raising if fetching fails.

• attr (str)

• id (int)

返回:

The object if found, or default if provided when not found. Returns None only if object_id is None and no default is given.

返回类型:

TypeVar(_FETCHABLE, bound= VoiceChannel | TextChannel | ForumChannel | StageChannel | CategoryChannel | Thread | Member | User | Guild | Role | GuildEmoji | AppEmoji) | TypeVar(_D) | None

抛出:

• TypeError -- Raised when required parameters are missing or invalid types are provided.

• InvalidArgument -- Raised when an unsupported or incompatible object type is used.

• NotFound -- Invalid ID for the object.

• HTTPException -- An error occurred fetching the object.

• Forbidden -- You do not have permission to fetch the object.

• InvalidData -- Raised when the object resolves to a different guild.

discord.utils.remove_markdown(text, *, ignore_links=True)

A helper function that removes markdown characters.

在 1.7 版本加入.

备注

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.

参数:

• 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.

discord.utils.escape_markdown(text, *, as_needed=False, ignore_links=True)

A helper function that escapes Discord's markdown.

参数:

• 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.

返回:

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

返回类型:

str

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

discord.utils.basic_autocomplete(values, *, filter=None)

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.

参数:

• values (Iterable[Any] | Iterable[str] | Iterable[int] | Iterable[float] | Callable[[Any], Iterable[Any] | Iterable[str] | Iterable[int] | Iterable[float] | Awaitable[Iterable[Any] | Iterable[str] | Iterable[int] | Iterable[float]]] | Awaitable[Iterable[Any] | 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.

• filter (Callable[[Any, Any], bool | Awaitable[bool]] | None) --

  An optional callable (sync or async) used to filter the autocomplete options. It accepts two arguments: the AutocompleteContext and an item from values iteration treated as callback parameters. If None is provided, a default filter is used that includes items whose string representation starts with the user's input value, case-insensitive.

  在 2.7 版本加入.

返回:

A wrapped callback for the autocomplete.

返回类型:

Callable[[Any], Awaitable[Iterable[Any] | Iterable[str] | Iterable[int] | Iterable[float]]]

示例

Basic usage:

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))

With filter parameter:

Option(str, "color", autocomplete=basic_autocomplete(("red", "green", "blue"), filter=lambda c, i: str(c.value or "") in i))

在 2.0 版本加入.

备注

Autocomplete cannot be used for options that have specified choices.

discord.utils.filter_params(params, **kwargs)

A helper function to filter out and replace certain keyword parameters

参数:

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

示例

>>> 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.

discord.utils.warn_deprecated(name, instead=None, since=None, removed=None, reference=None, stacklevel=3)

Warn about a deprecated function, with the ability to specify details about the deprecation. Emits a DeprecationWarning.

参数:

• name (str) -- The name of the deprecated function.

• instead (str | None) -- A recommended alternative to the function.
