这篇文章主要介绍Python怎么实现12306登录功能，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
python的五大特点：1.简单易学，开发程序时，专注的是解决问题,而不是搞明白语言本身。2.面向对象，与其他主要的语言如C++和Java相比, Python以一种非常强大又简单的方式实现面向对象编程。3.可移植性，Python程序无需修改就可以在各种平台上运行。4.解释性，Python语言写的程序不需要编译成二进制代码,可以直接从源代码运行程序。5.开源，Python是 FLOSS(自由/开放源码软件)之一。
具体代码如下所示：
#!/usr/bin/env python
import requests
import urllib.parse
import random
import time
req = requests.session()
import sys
import re
import urllib3
import getpass # 密文输入
urllib3.disable_warnings()
