eighth graders, up to a Silicon Valley hardware engineer who had no coding
experience, but who needed to do some test engineering.

Hi, Deb.
Ten years ago (or eleven?), I was completely new to Python. I could not begin
to understand over 90 percent of what I was reading here in comp.lang.python.
Still, I asked my newbie questions here. For the most part, I got excellent
responses. I think you're in the right place.

Thanks to both Ethan and Steven for their replies.
Steven: I was trying to use the interpreter and wasn't getting results that I
understood -- because I didn't know that __getslice__ was simply gone in Python
3. I implemented a __getslice__ method in my subclass that never got called.
Ethan:
I would like to build a multi-dimensional array that allows numpy-style
indexing and, ideally, uses Python's familiar square-bracket and slice
notations.
For example, if I declare a two-dimensional array object, x, then x[4,7]
retrieves the element located at the 4th row and the 7th column.
I find this programming pattern to be useful... but can it cause problems?

Surely, Pete, you meant to write if x == 99: ?
