Write a Python program to find the a number is prime or not

Without Function

# Input: number to check

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

# Prime numbers are greater than 1

if num > 1:

    # Check for factors

    is_prime = True

    for i in range(2, int(num**0.5) + 1):

        if num % i == 0:

            is_prime = False

            break

    # Output the result

    if is_prime:

        print(f"{num} is a prime number")

    else:

        print(f"{num} is not a prime number")

else:

    print(f"{num} is not a prime number")
