[Tutor] step value

[Vincent Balmori]

I am stuck on a question for Absolute Beginner's. I googled this and there have 
been others who have not understood the question and I am also not clear on the 
question he is asking. This function is a part of a tic tac toe program."Improve 
the function ask_number() so that the function can be called with a step value. 
Make the default value of step 1."



def ask_number(question, low, high):
    """Ask for a number within a range."""
    response = None
    while response not in range(low, high):
        response = int(input(question))
    return response
