Splitting a simple specific path on windows and linux

Question

Problem:

I'm having different behavior for Windows and Linux in the following case.

import os
path = '..\\file.hdf'
norm_path = os.path.normpath(path)
splitted_path = os.path.split(norm_path)
print(splitted_path)

Behavior

On Windows I get ('', 'file.hdf')

On Linux I get ('', '..\\file.hdf')

Question

Is there a better/specific way to use the os.path for this?

Workaround

Ok, it's easily fixed with norm_path.split('\\'), but that's not dynamic at all.

Answer 1

On Linux, paths are separated with a forward slash. If you want a platform-independent approach, I suggest using os.sep instead of backslash:

import os
path = '..' + os.sep + 'file.hdf'
norm_path = os.path.normpath(path)
split_path = os.path.split(norm_path)
print(split_path)
