How to remove a path prefix in python?

I wanted to know what is the pythonic function for this : I want to remove everything before the wa path. p = path.split('/') counter = 0 while True: if p[counter] == 'wa': break counter += 1 path = '/'+'/'.join(p[counter:]) For instance, I want '/book/html/wa/foo/bar/' to become '/wa/foo/bar/'.
A better answer would be to use os.path.relpath: http://docs.python.org/3/library/os.path.html#os.path.relpath >>> import os >>> full_path = '/book/html/wa/foo/bar/' >>> relative_path = '/book/html' >>> print(os.path.relpath(full_path, relative_path)) 'wa/foo/bar'
