1.Python代码

[root@njmon python]# cat username.py 
#!/usr/bin/env python
import os
import re
def get_username_func():
    global username
    global password
    file = open("/home/python/username.txt", "r")
    li = []
    for line in file.readlines():
        a = line.strip("/n")
        print('username is %s' % line.strip("/n").split(",")[0])
        print('password is %s' % line.strip("/n").split(",")[1])
        username = line.strip("/n").split(",")[0]
        print(username)
        password = line.strip("/n").split(",")[1]
        print(password)
        create_user_func(username,password)
        file.close()

def create_user_func(username,password):
    with open('/etc/passwd', 'r') as fd:
        for line in fd:
            matchusername = re.search(r'%s' % username, line, re.I)
    if not matchusername:
        os.system('useradd  %s -p %s' % (username,password))
        print('%s is create successfully' % username)
    else:
        print('%s is already exists.' % username)

def main():
    get_username_func()

if __name__ == "__main__":
    main()

[root@njmon python]# cat username.txt 
jack,passw0rd
aaron,passw0rd

3.执行效果，如果username存在，则不创建http://www.cndba.cn/hbhe0316/article/106636

[root@njmon python]# python username.py 
username is jack
password is passw0rd
jack
passw0rd
jack is create successfully
username is aaron
password is passw0rd
aaron
passw0rd
useradd: user 'aaron' already exists
aaron is create successfully
