Dealing with file paths on Windows, Mac and Linux

A easy way to deal with file paths is to use the python (3.4+) library pathlib. With pathlib we've just to use forward slashes (/). For example, the function Path() will convert forward slashes into the correct kind of slash for the current operating system:

from pathlib import Path
folder_path = Path("user/data")
print(folder_path)

Output:

#on Linux:
user/data

#on Windows:
user\data

If we need to add a sub path on to the path, we can use the / operator directly in the code:

from pathlib import Path
folder_path = Path("user/data")
print(folder_path / 'sub')

Output:

#on Linux:
user/data/sub

#on Windows:
user\data\sub
