方法1:
Python有一个类可以专门处理命令行参数,先看代码:
#!/usr/bin/env python # encoding: utf-8 from optparse import OptionParser
parser = OptionParser(usage="%prog [options]")
parser.add_option("-m","--machine",action="store",type="string",dest="machine",help="the machine to be check")
(options,args)=parser.parse_args() if options.machine: print options.machine
第一行用来初始化,
-m 为参数简写,—machine 为完整参数 store意思为将该参数存储, type为存储类型。dest为存储至哪个变量,默认为完整参数名,help为帮助时显示的内容
方法2:
使用getopt模块来解析
import sys import getopt def TestGetOpt(): try: opts, args = getopt.getopt(sys.argv[1:],'d:f:h',['days=','files=','help']) except getopt.GetoptError: usage() sys.exit() print (opts) print (args) for o, a in opts: if o in ("-h", "--help"): usage() sys.exit() elif o in ("-d", "--days"): day = a elif o in ("-f", "--files"): files = a print (day) print (files)
