Python in getopt module

In the daily work of the need to write a lot of Python script, when the function of the script is more, or the need for external input parameters, if the parameters
Name and parameter values can be executed in a way that makes the script seem more intuitive and convenient for you.

Python has a getopt module that handles command-line arguments.

function getopt (args,shortopts,longopts = [])

Args are generally sys.argv[1:]

Shortopys short Format (-)

Longopts long Format (–)//two bars

Execution method:

Python run_cmd.py-f iplist.txt-c ifconfig

Python run_cmd.py–file Iplist.txt–command ifconfig
The code is as follows:
