[FIXED] What does it mean to call a module with parameters "python mymod.py 50"?

Issue

What does it mean to call a module with parameters python mymod.py 50?

What does it mean and what will happen?

Solution

It simply means you pass 50 as string parameter to the python script mymod.py.

Below is a sample code of mymod.py to show what will happen.

import sys

print("Hello World")

print(sys.argv)

if len(sys.argv) > 1:
    print(sys.argv[1])

You could copy this code snippet into mymod.py and test in your PC by running

python mymod.py 50

and you may get result like the following:

Hello World
['test.py', '50']
50

As a result, in mymod.py we could get the passed parameter from the built-in sys.argv var.

Hope it helps.
