脚本名字：adduser.py

import subprocess
import sys
from randpass import gen_pass
def adduser(username, password, fname):
    data = """user information:
%s: %s
"""
    subprocess.call('useradd %s' % username, shell=True)
    subprocess.call(
        'echo %s | passwd --stdin %s' % (password, username),
        shell = True
    )
    with open(fname, 'a') as fobj:
        fobj.write(data % (username, password))

if __name__ == '__main__':
    username = sys.argv[1]
    password = gen_pass()
    adduser(username,password,'./user.txt')

执行脚本：
# python3 adduser.py boy
# python3 adduser.py girl
