#Moving up/down dir structure print os.listdir('.') # current level print os.listdir('..') # one level up print os.listdir('../..') # two levels up # more complex example: # This will walk the file system beginning in the directory the script is run from. It # deletes the empty directories at each level for root, dirs, files in os.walk(os.getcwd()): for name in dirs: try: os.rmdir(os.path.join(root, name)) except WindowsError: print 'Skipping', os.path.join(root, name)
