getopt实现传参自动识别

Posted 2021-01-30 kevincaptain

test.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import getopt
import sys
#-h-f-v为了下面的识别
opts,args = getopt.getopt(sys.argv[1:],‘-h-f-v‘,[‘help‘,‘filename=‘,‘version‘])
#print(opts)
for opt_name,opt_value in opts:
    if opt_name in (‘-h‘,‘--help‘):
        print("[*] Help info")
        sys.exit()
    if opt_name in (‘-v‘,‘--version‘):
        print("[*] Version is 0.01 ")
        sys.exit()
    if opt_name in (‘-f‘,‘--filename‘):
        fileName = opt_value
        print("[*] Filename is ",fileName)
        # do something
        sys.exit()

运行test.py -v

打印 "[*] Version is 0.01 "
