Python ZipFile path separators

Question

If I am unzipping a Zip file with the Python ZipFile library, where the file was created on Windows, but my code is running on Unix-like, will the path separators always be Unix-style?

Answer 1

Internally, ZipFile stores forward slashes as required by the zip file specification.

Externally, they get translated using os.sep so it will match what is normally expected on a given platform.
