Integer Errors in Python

Question

So I made a very simple program that counts down from 99 (sings 99 bottles of beer) but I keep getting 1 of 2 errors

#!/usr/bin/env python
print("This program sings the song 99 bottles of beer on the wall")
lim = input("What number do you want it to count down from?")
def sing():
    global lim
    while int(lim) >= 0:
        if int(lim) != 1 or int(lim) != 0:
            print(lim, "bottles of beer on the wall", lim, "bottles of beer")
            print("Take one down pass it around...")
            print(lim, "bottles of beer on the wall")
            input("\nPRESS ENTER\n")
            lim -= 1
sing()
TypeError: unsupported operand type(s) for -=: 'str' and 'int'

Then, when I change lim -= 1 to int(lim) -= 1, it says SyntaxError: illegal expression for augmented assignment

Answer 1

You need to covert lim from a string to an integer. Try this:

lim = int(input("What number do you want it to count down from?"))

Answer 2

If you're using Python 2.x (you don't specify), use raw_input instead.

lim = int(raw_input("What number do you want it to count down from?"))

From there, you can remove all the checks to int(lim), as lim is already an integer.
