tools/autopep8.sh corrupts Python format strings in Python 3.12 environments

[bneradt]

I noticed this when I switched my dev environment yesterday from fedora:38 to fedora:39. It seems with my fedora:39 environment, the cmake --build build --target autopep8 target changes many (or all?) of the .py file's format. This is obviously terrible as we can't have different dev environments formatting differently between them.

I'm not sure what the issue is yet. The pip freeze is identical between them:

fedora:38:

╰─➤  pip freeze
autopep8==1.5.3
pycodestyle==2.6.0
toml==0.10.2

fedora:39:

╰─➤  pip freeze
autopep8==1.5.3
pycodestyle==2.6.0
toml==0.10.2

I suppose this is likely due with the upgrade from Python 3.11 in fedora:38 to Python 3.12 in fedora:39. I'm not sure yet however.

I think the following autopep8 issue is the cause:

hhatto/autopep8#712

Looking at the diffs generated with Python 3.12 locally, it seems like they do indeed relate to format strings.

We addressed this issue by moving to yapf from autopep8:
