Allow the user to enter any number. You have to test to see if it is a prime number or not.

A prime number is one which divides cleanly by 1 and itself only. For example 7 is a prime number.

To test if a number is prime you must test every number from 2 to the one less than the number your testing. For example –

7 % 2
7 % 3
7 % 4
7 % 5
7 % 6

To help, you may wish to use the following if statement –

if x % y == 0:
    print ("This divides cleanly")
else:
    print ("it does not divide cleanly")
