[Tutor] Step Value

[James Reynolds]

Without looking at your code,

What is it that you know that's wrong about it? Are you getting a return
value which you know is incorrect, is the program throwing error and you
aren't sure why? or do you just suspect it is wrong but you aren't sure?

When posing a question, it's helpful to know the things above because those
answering might not know exactly what your problem is.

with regards to the step value of range, here,  "if response in range(low,
high, 1)" the default step value of range() is 1, so you don't need to have
that. range(1,3) will give you a list [1,2], for example.
