L 3

this lesson i learned for loops and while loops.

here is a while loop i wrote
num = int(input("enter a number: "))

i = 2
while i < num:
    if num / i == 0:
        isdevisable = True
        print("{} is devisable by {}".format(num,i))
        i += 1
if isdevisable:
    print("{} is not a prime number".format(num))
else:
    print("{} is a prime number".format(num))
