Classifying a range of numbers as either prime or composite

Question

Write source code that classifies all numbers from 2 to 20 as being either a composite number or a prime number.

I am only able to do a code where it's only one number not a range of numbers

num=2
if num > 1:
    for i in range(2, int(num/2)+1):
        if (num % i) == 0:
            print(num,"is a composite number")
        break
    else:
        print(num, "is a prime number")

Please add code which you created to your question. – Daweo Jun 15 '21 at 14:29 — Daweo, Jun 15 '21 at 14:29

Try this code snippet below:

prime = [x for x in range(2, 21) if not [y for y in range(2, x) if x % y == 0]]
