I'm absolutely new to Python and programming in general so it'd be helpful if someone can give very beginner friendly help. I'm trying to get the sum of prime numbers upto say 50.

I used the below code but it adds additional 2 on my sum. for example sum of prime number upto 50 should be 326 but I get 328 as my output

upto = int(input("Find sum of prime numbers upto : "))

sum = 0

for num in range(2, upto + 1):

    
    for i in range(2, num):
        if (int(num % i) == 0):
            break;

    #If the number is prime then add it.
    else:
        sum += num

print("\nSum of all prime numbers upto", upto, ":", sum)
