Python – Module sys

The python sys module provides functions and variables which are used to manipulate different parts of the Python Runtime Environment. It lets us access system-specific parameters and functions

import sys

Here are the most useful functions for me:

sys.exit()

Exit from the python code. All code after this will not be executed

import sys
sys.exit()

sys.argv

Return a list of values with all the arguments you entered through command line.

Be aware the first element is the name of your Python’s script. You will need to slice it with sys.argv[1:] to take all arguments except the first one (0 is the first list’s member).

#! python2.7
import sys
arguments=sys.argv[1:]
print(sys.argv)
for a in arguments:
    count=1
    dico = {}
    dico['arg' + str(count)] = a
    print('My name is %s') %(a)
    count+=1

If you enter in command line the the following code

py 'name_of_this_script.py' totoro nemo dory pascal

You will have the following result
