Function signature mismatch for functools.reduce between C implementation, Python implementation, and online documentaion #102757
Description
Documentation
(A clear and concise description of the issue.)
The function signature mismatch for functools.reduce:
-
C implementation:
_initial_missing = object() @overload def reduce(function, iterable, /): ... @overload def reduce(function, iterable, initial=_initial_missing, /): ...
-
Python implementation:
_initial_missing = object() @overload def reduce(function, sequence): ... @overload def reduce(function, sequence, initial=_initial_missing): ...
Argument change: iterable -> sequence.
-
Online documentation:
def reduce(function, iterable, initializer=None): ...
Argument change: initial -> initializer.
