Hi friends! How do you create a code that checks if a number is a prime number or not in python?

Answer 1

This code I take from this book: "Introducción a la programación con python", Chapter 5, 2.6, if you know spanish, I recommend, I'm studying from this book, I'm newbie, XD,
This code is to check if number is prime or not with "for-in" bucle, enjoy it XD

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

i_think_is_prime = True
for divider in range(2, num):
if num % divider == 0:
i_think_is_prime = False
break

if i_think_is_prime:
print("The number", num, "is prime")
else:
print("The number", num, "is not prime")

Answer 2

Use modulus operator to check divisibility.

Use for loop to loop over the numbers smaller than the number being checked.
