Functools¶

Some classes that are applied to functions and change the way the function is called. Some of those listed are present in the functools [0] module.

Functools for one function¶

complement(), negate the return value of the function. Equivalent to lambda func: not func.
flip(), reverse the order of the arguments passed to the function. Equivalent to lambda func: lambda *args, **kwargs: func(*list(reversed(args)), **kwargs)
functools.lru_cache(), cache the return value of a function.
functools.partial(), partially set the arguments of a function.
partial(), partially set the arguments of a function; also accepting placeholders.
functools.partialmethod, same as functools.partial() but works on methods.
