I was testing my program in github workflow and i detected a bug. i was opening a file in windows:

f = open(os.path.dirname(__FILE__) + '/some/file.txt')

means the file path will be `C:\some\path/some/file.txt`.

but i received OSError. why? because in the above path, we have both `/` and `\`.

I think this bug should be fixed by converting all of `/`s to `\` in file paths automatic.

Update: i only tested this bug in `3.6` and `3.7` i'm not sure about newer versions. but i think this bug also is in them.

I think this bug should be fixed by converting all of `/`s to `\` in file paths automatic **When os is windows**.

"C:\some\path/some/file.txt" is a valid file path. The Windows file API normalizes most paths, except for verbatim paths that start with exactly "\\?\". Path normalization includes replacing forward slashes with backslashes.

If you provide the complete traceback, I may be able to help diagnose the problem, but not here. Please ask for help on or
