I need to write a program that the user input numbers and stops when the user enter 0, them it should see which number is a prime number and sum only the prime numbers.
I wrote it but it counts even if the number isn't a prime.
please advise

First of all, you are putting the definition inside the while loop, this will not disrupt your code, but make it significantly slow.
Second, you are using statements like if False, that will ALWAYS return False and the code wont run
So, instead of using if False try if not prime(num), then put an else statement for the other half. You don't even need the sum_of_primes = 0 +sum_of_primes, you can just remove that so you can finally replace the if-else with:
if prime(num):
sum_of_primes = sum_of_primes + num
