The sum of prime number is incorrect

Question

The code is not returning the sum of of the prime numbers, what I'm i doing wrong?

the_sum = 0
for number in range(20):
    if number > 3:
        for i in range(2,number):
            if (number%i)==0:
                break
        else:
            the_sum += number
            print (the_sum)

Answer 1

2 is a prime number, you need to include that. also 3, you are checking > 3 , it should be >=

the_sum = 0
for number in range(2,20):
    for i in range(2,number):
        if (number%i)==0:
            break
    else:
        the_sum += number
print(the_sum)
