[Python] ZeroDivisionError: integer modulo by zero [closed]

I was trying to create a simple python code for finding HCF of two numbers using Euclid's method

a = int(input('Enter the first number: '))
b = int(input('Enter the second number: '))
while b != 0:
rem = int(a) % int(b)
a = b
b = rem
print('The HCF is', a)


and I got a error like

Traceback (most recent call last):
File "C:\Users\PycharmProjects\HCF.py", line 4, in <module>
rem = int(a) % int(b)
~~~~~~~^~~~~~~~
ZeroDivisionError: integer modulo by zero
