Long time did not update the blog

 

Recently for a new job have time to organize a

In the command line CMD file in the implementation process and how to pass parameters to identify

Here wrote a class

The method is used to output usage information to help

Case_cmd test method is used to identify process parameters passed with -d -v command line execution　　　

opts, args = getopt.getopt(sys.argv[1:], "hd:v:")

This line is an execution file acquiring parameters may identify h d: v: three kinds of parameter format suffix

I can give you a look effect

No input parameters:

 

 Input -h:

 

 Enter the -v and -d:
