Python Packages.'import Sys' Vs 'from Sys Import Argv'

I'm trying to use 'argv' into my python script. For this i'm using following code: from sys import argv script, file_name = argv print(file_name) python3 e.py e.txt This code work

Solution 1:

Import sys does not give you direct access to any of the names inside sys itself To access those you need to prefix them with sys:

sys.argv
sys.exit()

If you want use argv instead sys.argv try

from sys import *

Solution 2:

@Aman, have a look at the following 2 code examples.

Check this beautiful https://www.python.org/dev/peps/pep-0008/?#imports for more information about imports.

sys_file_name.py »

import sys
