python命令行-argparse模块

argparse模块优点：

argparse是optparse模块的升级版，与optparse模块相比，argparse模块使用更加简单便捷。

执行界面：

 

 command_argparse.py

import argparse

def start():
    parser = argparse.ArgumentParser()
    parser.add_argument("-u","--user",dest="User",type=str,default="root",help="target user")
    parser.add_argument("-p","--password",dest="Pwd",type=str,help="target password")

    print(parser.parse_args())

if __name__ == '__main__':
    try:
        start()
    except KeyboardInterrupt:
        print("interrupted by user, killing all threads...")
