Maybe you are converting the input to an integer, you should try using float to check if the input is a number, remember that the input can also be a float, if you use int then it would round the number and your response would not match the given in the kata, and then when you return your response, convert it to an int before sending it.

you must not forget the float type

Your code has a bug, not a kata issue. Print the input to help you debug your code.

On the python attempty for this project, I keep on getting an error that says it should be 66 and not 56, I am not sure where I am going through as I am only getting this one error and all the others seem to be a pass.
