Using chdir to move up a directory in Python -

want move 1 directory given directory. achieve doing:

import os os.chdir(given_dir) os.chdir('..') 

but, wondering if there better more explicit way using (ideally) 1 statement or if there exists built-in feature may not aware of.

how about

import os, os.path print os.chdir(os.path.join(given_dir, os.pardir)) 

or

os.chdir(os.path.dirname(given_dir)) 

(as selcuk suggested)
