Question

I’m trying out Python, and, in my very tired state, can’t seem to find the problem with the code below:

import sys

def printNum(x):
    y = 0
    while y < x:
        print "Number: ", y
        y = y + 1

printNum(sys.argv[1])

So, I’m trying to get it to print out y x times. x is passed as a parameter. The loop never ends and I don’t know why!

Answer 1

Currently this code will paste a str into printNum, but printNum treats the input (x) like an int. To fix this, convert the input to an int:

printNum(int(sys.argv[1]))
