_functools

Tools that operate on functions.

Classes

partial

partial(func, *args, **keywords) - new function with partial application
    of the given arguments and keywords.

args = <member 'args' of 'functools.partial' objects>
  tuple of arguments to future partial calls

func = <member 'func' of 'functools.partial' objects>
  function object to use in future partial calls

keywords = <member 'keywords' of 'functools.partial' objects>
  dictionary of keyword arguments to future partial calls

Functions

cmp_to_key

cmp_to_key(...)

  Convert a cmp= function into a key= function.

reduce

reduce(...)

  reduce(function, iterable[, initial]) -> value

  Apply a function of two arguments cumulatively to the items of a sequence
  or iterable, from left to right, so as to reduce the iterable to a single
  value.  For example, reduce(lambda x, y: x+y, [1, 2, 3, 4, 5]) calculates
  ((((1+2)+3)+4)+5).  If initial is present, it is placed before the items
  of the iterable in the calculation, and serves as a default when the
  iterable is empty.
