本文实例讲述了python采用getopt解析命令行输入参数的方法,分享给大家供大家参考。
具体实例代码如下:
import getopt import sys config = { "input":"", "output":".", } #getopt三个选项,第一个一般为sys.argv[1:],第二个参数为短参数,如果参数后面必须跟值,须加:,第三个参数为长参数 #是一个列表, opts, args = getopt.getopt(sys.argv[1:], 'hi:o:d', [ 'input=', 'output=', 'help' ] ) #参数的解析过程,长参数为--,短参数为- for option, value in opts: if option in ["-h","--help"]: print """ usage:%s --input=[value] --output=[value] usage:%s -input value -o value """ elif option in ['--input', '-i']: config["input"] = value elif option in ['--output', '-o']: config["output"] = value elif option == "-d": print "usage -d" print config
输入的参数:
--input=c:\temp\aa -o c:\temp\output -d
打印的结果:
usage -d {'input': 'c:\\temp\\aa', 'output': 'c:\\temp\\output'}
希望本文所述对大家的Python程序设计有所帮助。
