The difference between sys.argv & argv?

Question

I don't understand the difference between sys.argv and just argv, Nothing online gives me the concept that I understand. if both are the same! When do we use sys.argv and when to use argv ?

if not what is the sys.argv. I've idea what is the argv.

Answer 1

They're the same thing, it just depends on how you write the import statement.

import sys

If you write this, then you must reference sys.argv.

from sys import argv
from sys import *

If you write either of those, then you can write simply argv without the sys. qualifier.
