What does sys.argv do on python?

Answer 1

sys.argv is a way to access command line arguments in Python. sys.argv is an array of all the command line parameters, where the first value is the name of the file being run.

For example, let's say you have a python script named example.py that looks like this:

import sys

print(sys.argv)

This script will simply print the command line parameters in an array. If, for example, you run the script from a command line as

python example.py param1 param2

the output will be

['example.py', 'param1', 'param2']
