gh-127541: Update os.walk example #127765

totosuki · 2024-12-09T15:20:48Z

I updated the example to exclude __pycache__ directories instead of CVS.
While the issue suggested replacing CVS with .git, a comment pointed out that .git is usually found only in the root directory, making it not equivalent to CVS, which can appear in multiple subdirectories.
On the other hand, __pycache__ directories often appear across various levels of a directory tree, making them a more practical modern example!

This is a better example. But look also at the fwalk() example and docstrings.

Thank you!
You're absolutely right that going into .git isn't ideal. I'll update it to python/Lib/xml now.

Hi @gpshead , just pinging in case this PR was missed. Appreciate any final review!

gpshead

thanks! and good practical idea to use __pycache__ for the example directory to skip.
