sum of prime numbers python program?

Write a function sum_primes(N) that adds all the prime numbers (that is: integers that are only divisible by 1 and themselves) between 1 and argument N and returns the result. Write a program that asks the user to enter a number Q and prints onto the console the sum of all prime numbers up to Q, using the sum_primes() function.

can someone answer this for me please

    Hi, Adriana. Have you had a go at coding this? I suggest you simplify: start by writing a program that determines whether or not a number is prime. That would be a good building block to start with. Can you do that?

      In your code, I think it should be
      for i in range (1, n):
        if i > 1:
      Forget about num. Use i instead. Delete "num = n[i]" - this makes no sense ay all!
      Good luck!
