functools

Built-in functional helpers. Works without Shared Library research.

functools.reduce(fn, iterable, initializer?, /)

Combine an iterable into one value by repeatedly calling pure fn(total, item); callbacks cannot suspend the script or mutate game state. With no initializer, the first item becomes the initial total; empty iterables then raise. Empty-with-initializer and singleton-without-initializer perform no callback call. Also available as the global reduce().

Returns: any

functools.total_ordering(cls, /)

Class decorator that preserves the class object and fills missing ordering methods from __eq__ plus one of __lt__, __le__, __gt__, or __ge__. Explicit methods are never replaced. Applying it mutates the local class namespace.

Returns: any

functools.wraps(wrapped, /)

Return a decorator that preserves the wrapped callable’s supported name, qualified name, docstring, custom attributes, and __wrapped__ link while keeping the wrapper’s call behavior. Applying the returned decorator mutates only that local wrapper function.

Returns: any
