:#Now lets make the same script EVEN more intelligent. Make a copy of '''lab2f.py''' and call it '''lab2g.py'''. Now modify '''lab2g.py''', add a if statement to the script that checks to see if a argument was entered. If a argument was entered use that number for the timer, if no argument was entered, timer should equal 3.

NOTEWARNING: When using arguments as number numbers/integers or performing math on arguments you must wrap them in the int() function: number = int(sys.argv[1])NOTEWARNING: Remember to check the number of arguments using len(sys.argv) in a if statement

::*The script should have a Shebang line::*The script should import sys::*The script should use a variable named timer with the value of 3 if no arguments are entered ::*The script should use a variable named timer with the value of int(sys.argv[1]) if arguments are entered ::*The script should have a while loop that repeats until timer equals 0::*The script should print the EXACT OUTPUT as shown
