How to write to a directory os agnostic?

Question

I am developing on a Windows machine some code that will be run in a Linux environment. I know the path of the file in Linux will be /tmp/ that I need to write to. The accepted answer to this question does not work on Windows: Platform-independent file paths?

when I try open(path.join('tmp', 'fileToOpen.txt'), 'w') I get "FileNotFoundError: [Error 2] No such file or directory: 'tmp\fileToWrite.txt'"

How can this be resolved?

As @Tomerikoo and @jakub pointed out, you want to use the pathlib and tempfile modules in Python:

• tempfile.gettempdir() will retrieve the location and
• pathlib.PurePath will join the filename to that path in an OS agnostic fashion.

You'll end up with something like:

open(PurePath(gettempdir(), 'fileToOpen.txt'), 'w')
