Yes. For future use, the easiest way to answer a question like that is to
do:
>>> help([].index)
Help on built-in function index:
index(...)
L.index(value,
What's b.index(x) do?
I'm guessing the for a list Delta = ["a,"b","c"], you get
Delta.index("b")

Danny,
Yes, it looks like that is a valid unittest for a circular buffer. An
enhancement is to modify the accessors:

In some cases it is. The Rekursiv computer by Linn systems had

In a language like C it would help but in Python there's not much

Yes you can always write a program without classes but it may be a

Especially if its a big program.

Hi John,
Thanks Kent I kind of see what you are trying to explain to me, it makes it
easier by trying the different combination.
So even is I change the first line to
import time
My script is still not working properly, I am obviously missing a statement
somewhere, the script return:
Enter a number: 25
You are just a little confused about imports.
If I
>>> import time
then the name 'time' is bound to the time module:
>>> time
The time() function is an attribute of the time module:
>>> time.time
>>> time.time()
1112296322.9560001
Alternatively, I can import the time function directly:
