Step value and function

[israphelr]

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 a
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.

Thanks in advance.

Trivial and redundant examples, but you get the point:

def doit(start, stop):
for i in range(start, stop):
print i

def doit_step(start, stop, step):
for i in range(start, stop, step):
print i

At work:

py> doit(2, 11)
2
3
4
5
6
7
8
9
10
py> doit_step(2, 11, 2)
2
4
6
8
10
