Built-in function `range` params discrepancy across versions

I'm sorry if this has already been reported. I'm sure it's very low on any list of priorities but it should be an easy one.

I noticed that when doing a Google search for "python built in functions" I am presented with two official results:

1. functions https://docs.python.org/3/library/functions.html
2. stdtypes https://docs.python.org/3/library/stdtypes.html

On the functions page, clicking on range takes you to https://docs.python.org/3/library/functions.html#func-range . It looks like, as of 3.11, range accepts step as a kwarg. This is inconsistent with the stdtypes page which shows step as an optional, positional arg through 3.13.

functions:

• 3.10 https://docs.python.org/3.10/library/functions.html#func-range
• 3.11 https://docs.python.org/3.11/library/functions.html#func-range
• 3.12 https://docs.python.org/3.12/library/functions.html#func-range
• 3.13 https://docs.python.org/3.13/library/functions.html#func-range

stdtypes:

• 3.10 https://docs.python.org/3.10/library/stdtypes.html#range
• 3.11 https://docs.python.org/3.11/library/stdtypes.html#range
• 3.12 https://docs.python.org/3.12/library/stdtypes.html#range
• 3.13 https://docs.python.org/3.13/library/stdtypes.html#range

source:

• 3.10 https://github.com/python/cpython/blob/3.10/Objects/rangeobject.c#L159
• 3.11 https://github.com/python/cpython/blob/3.11/Objects/rangeobject.c#L157
• 3.12 https://github.com/python/cpython/blob/3.12/Objects/rangeobject.c#L156
• 3.13 https://github.com/python/cpython/blob/3.13/Objects/rangeobject.c#L158

I didn't see any mention of this change in What’s New In Python 3.11 and it surprised me that a built-in would be changed in such a way.

I pulled a 3.11 docker image and it would seem step is not a kwarg.

docker run -it --rm python:3.11
Python 3.11.10 (main, Oct 19 2024, 04:02:01) [GCC 12.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> range(1, 1, step=1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: range() takes no keyword arguments

tl;dr - The functions page incorrectly states that the range function accepts step as a kwarg.

バージョン3.10から3.13について、functions および stdtypes ドキュメントページの range の記述を比較し、リンクされている rangeobject.c ソースを使って呼び出し動作を検証してください。リンクされている PR gh-125945、gh-137652、gh-137653 を確認してください。ドキュメントに step がキーワード引数として受け入れられると記載されなくなれば、作業は完了です。
