Subject: Minor C API documentation improvements. (GH-17698)
X-Git-Tag: v3.7.7rc1~125
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=090bc148834aa4c92c683c2c07be572c31dd1b68;p=thirdparty%2FPython%2Fcpython.git

Minor C API documentation improvements. (GH-17698)

The added parentheses around the PyIter_Next assignment suppress the following warning which gcc throws without:
```
warning: using the result of an assignment as a condition without parentheses [-Wparentheses]
```
The other change is a typo fix
(cherry picked from commit 5c7ed7550ec2da16d7679e538fcd7c1a5631811f)
