Hi there. So I have a challenge in the Python book I am using (python
programming for the absolute beginner) that tells me to improve an ask_number()
function, so that it can be called with a step value, and I havn't
been able to find out yet what's meant by a step value, but i'll keep
looking of course. I'd just be grateful if someone could illimunate
this for me.
def ask_number(question, low, high):    """Ask for a number within a range."""    response = None    while response not in range(low, high):        response = int(raw_input(question))    return response
Thanks in advance.
