can you code this in python using if statmens and explain with docstrings thanks

Your script should behave as follows: 1. If is divisible (leaves remainder ) by only , print 'a'. 2. If is divisible by only , print 'b'. 3. If is divisible by both and , print 'ab'. 4. If neither of the above statements hold true, print 'none'. Preconditions (something you can assume is true): a, b, and num are all positive integers greater than or equal to one. the given values are a = 5, b = 5, num = 5
