Platform-independent file paths?

Question

How can I use a file inside my app folder in Python? Platform independent of course... something similar to this:

#!/bin/sh mypath=${0%/*} LIBDIR=$mypath/modules 

Answer 1

You can use os.path and its functions, which take care of OS-specific paths:

>>> import os >>> os.path.join('app', 'subdir', 'dir', 'filename.foo') 'app/subdir/dir/filename.foo' 

On Windows, it should print out with backslashes.
