Danny, Thanks for the informative response. After I sent the email I realized that a circular buffer is a FIFO with fixed capacity, and that is what I want to implement. I think I recall seeing a recipe in the Python Cookbook (1st). If you or anyone else know of other recipes/implementations

You are just a little confused about imports. If I import time then the name 'time' is bound to the time module: time module 'time' (built-in) The time() function is an attribute of the time module: time.time built-in function time time.time() 1112296322.9560001 Alternatively, I can import

I was wondering, can you make a program the uses alot of classes do the exact same thing with out useing classes? Yes you can always write a program without classes but it may be a lot more work and its likely to be a lot harder to maintain. Especially if its a big program. However if you

Let me make sure I understand. Let's imagine that we have such a CircularQueue, with methods: push(element) pop() isEmpty() [example unittest code] Danny, Yes, it looks like that is a valid unittest for a circular buffer. An enhancement is to modify the accessors:
