Python uses getopt to parse command line input parameter instances _python

The example of this article is about Python using getopt to parse command line input parameters and share them for everyone's reference.

The specific example code is as follows:

Import getopt 
import sys 
 
config = {" 
  input": "", 
  "Output": ".", 
   
} 
 
#getopt三个选项, the first is generally SYS.ARGV [1:], the second parameter is a short parameter, if the parameter must be followed by a 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, long parameter is--, short parameter is-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  

Parameters entered:

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

Results of Printing:

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