Thanks for the pyramid example, that's a good one. As a calibration point, it took me from 16 minutes past the hour when I read your post to 26 past the hour to complete. And the ten minutes included two interruptions where I had to go to another office. And 3 more minutes to write this post. I did google "2d array python" when the array initialization I used at first didn't work. (I'm new to python and had not done a 2d array in it yet.) Works fine, dumps the result in formatted output, and accepts any positive number as an argument to pyramid size, odd or even.
