Prime Numbers python

Question

I\'m a beginning programmer in python and have a question about my code I\'m writing:

number = int(input(\"Enter a random number: \"))

for num in range(1, n         


        

Answer 1

With if (num % i) == 0: you go to the else block for every num, which is not a multiply of 2, as you start i with 2, thus printing num. I got all odd numbers printed with your code.

You can use something like this:

number = int(input("Enter a random number: "))

for num in range(1, number + 1):
    prime = True
    for i in range(2, num):
        if (num % i) == 0:
            prime = False
            break
    if prime:
        print(num)

It sets prime to False when it encounters a divisor without rest.
