Python uses getopt parsing command-line input parameter instances

In this paper, we describe Python's method of using getopt to parse command line input parameters and share them for your reference.

The specific instance code is as follows:

Import getopt Import sys  config = {   "input": "",   "Output": ".",    }  #getopt三个选项, the first one is generally sys.argv[1:], The second parameter is a short parameter, if the argument must follow the value, add:, the third parameter is a long parameter #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, the long parameter is--, the short parameter is-for option, the value in the 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  

Input parameters:

--input=c:\temp\aa-o c:\temp\output-d

Printed results:

usage-d{' input ': ' c:\\temp\\aa ', ' Output ': ' C:\\temp\\output '}

Hopefully this article will help you with Python programming.
