#!/usr/bin/python3
username = 'joe'
# generate passphrase
pw_length = 6
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')

我该如何解决这个错误：
bash-3.00# python ./pass2.py
Traceback (most recent call last):
File "./pass2.py", line 6, in ?
phrase = subprocess.check_output(['pwgen', str(pw_length), '1'])
NameError: name 'subprocess' is not defined

Subprocess is a module. You need to import it.
子进程是一个模块。你需要导入它。
Put this as the second line in your file: import subprocess
将此作为文件中的第二行： import subprocess
