Help! Function doesn't run

[bwdu]

Hi everyone! I am trying to find 1000th prime number with this function, there is no any errors but it doesn't run and I don't know why. Can you help me?

import sys


def thousandprime():
    for i in range(sys.maxsize**10):
        primes = []
        if i % 2 != 0 and i % 3 != 0 and i % 5 != 0 and i % 7 != 0:
            primes.append(i)
        elif len(primes) == 1000:
            print(primes[-1])
            return 
           
thousandprime()
