Multidimensional Iterators in NumPy

[[deleted user]]

I am a Python novice, so I am having trouble seeing the point at which the Python multi-dimensional array (list) support that is built into the language runs out of steam. When does one need to consider NumPy? Is this add-on library strictly for scale/performance or does it offer additional function too?

This is one of the first examples I have seen that shows off the true power that an Iterator pattern can offer.

Seems very similar to C++, C#, and database iterators. I wasn't aware that iterators was a formal pattern but that makes perfect sense.

I don't know anything about NumPy, so I didn't understand why this is special. I think I've only used two dimension table iterators, so thinking about a 3-D table and iterators was new for me.
