TypeError: '<' not supported between instances of 'str' and 'int'

i am just experimenting while loop and what i am trying to do is to make the user input his Hight and it should be bigger than zero but when the user input number less than 0 two time the following error show:

TypeError: '<' not supported between instances of 'str' and 'int'

so what wrong with my code?

import sys

def two_by_two(num1, num2):
    val = num1 * num2
    return val
hight = input("what is your hight?  ")
hight = int(hight)
attempt_count = 1
while hight < 0:
    if attempt_count > 3:
        sys.exit("too  many")
    hight = input("The number bigger than ZERO, what is your hight?  ")
    attempt_count += 1

print(two_by_two(hight, 5))

I like your approach to this, nice work!

You only forgot one tiny thing (and you may have discovered it already). Convert the second input to an integer (see below).

Cheers to you! JM

import sys

def two_by_two(num1, num2):
    val = num1 * num2
    return val
hight = input("what is your hight?  ")
hight = int(hight)
attempt_count = 1
while hight < 0:
    if attempt_count > 3:
        sys.exit("too  many")
    hight = input("The number bigger than ZERO, what is your hight?  ")
    hight = int(hight) # this was added to do the conversion.
    attempt_count += 1

print(two_by_two(hight, 5))
