[docs] Is this sample code not too clear

Hi, I saw a pice of code about “command line argument”:

...

...

import sys print(sys.argv) ['demo.py', 'one', 'two', 'three']

on this page: https://docs.python.org/3/tutorial/stdlib.html#command-line-arguments It shows how to get a list of parameters and looks like it's in interactive mode. But I can't do the same thing in interactive mode, sys.argv is always return empty list, unless I put these code in a script and execute it. Does this mean this sample code not too clear?
