Prime number in Python

#Write your code below this line 👇
def prime_checker(number):
    for num in range (2, number):
        if num % number == 0:
            print("It is not a prime number")
        else:
            print("It is a prime number")

n = int(input("Check this number: "))
prime_checker(number=n)

How can I print a text that number is prime or not only once?

Solution 1:

Fix

number % num == 0 and not num % number == 0

A number isn't prime the moment you find a number that doesn't divide it, but only when you have tested all and none divides it

Use for/else construction, it goes into else if no break has been used

def prime_checker(number):
    for num in range(2, number):
        if number % num == 0:
            print("It is not a prime number")
            break
    else:
        print("It is a prime number")

Note that this only fixes your way to do, but that isn't the optimal way to check if a numbre is a prime one, at least, ending range at square root of number, and directly verifying division by small numbers like 2,3,5,7
