Raindrops

Instructions

Your task is to convert a number into its corresponding raindrop sounds.

If a given number:

• is divisible by 3, add "Pling" to the result.
• is divisible by 5, add "Plang" to the result.
• is divisible by 7, add "Plong" to the result.
• is not divisible by 3, 5, or 7, the result should be the number as a string.

Examples

• 28 is divisible by 7, but not 3 or 5, so the result would be "Plong".
• 30 is divisible by 3 and 5, but not 7, so the result would be "PlingPlang".
• 34 is not divisible by 3, 5, or 7, so the result would be "34".

How this Exercise is Structured in Python

This exercise is best solved with Python's % (modulo) operator, which returns the remainder of positive integer division. It has a method equivalent, operator.mod() in the operator module.

Python also offers additional 'remainder' methods in the math module. math.fmod() behaves like %, but operates on floats. math.remainder() implements a "step closest to zero" algorithm for the remainder of division. While we encourage you to get familiar with these methods, neither of these will exactly match the result of %, and are not recommended for use with this exercise.

The built-in function divmod() will also give a remainder than matches % if used with two positive integers, but returns a tuple that needs to be unpacked.
