Repeat question (for loop)

[rs74]

Trying to make a small program where a user can answer basic questions (1+1 etc). But the questions should be random, in my code, no random numbers are generated. Is the for loop in wrong place?

import random

from random import randrange



x = random.randrange(0, 101)

y = random.randrange(0, 101)

sum = (x + y)

for sum in range(1, 5):

	a = int(input(f'What is {x} + {y}? '))

if a == sum:
    	print('Correct')

else:
    	print(f'Not correct, the correct answer is {sum}.')
