#!/usr/bin/python3

phrase = subprocess.check_output(['pwgen', str(pw_length), '1'])
phrase = phrase.decode('utf-8').strip()

dev_null = open('/dev/null', 'w')
passwd = subprocess.Popen(['sudo', 'passwd', user], stdin=subprocess.PIPE,
                          stdout=dev_null.fileno(),
                          stderr=subprocess.STDOUT)
passwd.communicate( ((phrase + 'n')*2).encode('utf-8') )
if passwd.returncode != 0:
    raise OSError('password setting failed')

Subprocess is a module. You need to import it.

Put this as the second line in your file: import subprocess
