I finally took a moment to put my buffered socket class, bufsock.py, on a

It's a wrapper class for python sockets.
It should reduce tinygrams, as well as provide a more convenient

Teach that Python emphasizes readability. Perhaps talk about bugs /
lines_of_code being roughly a constant. Then talk about the fact that
Python generally takes fewer lines of code to express the same thing. This
implies fewer bugs for many projects.

tests working using the second expression above, but I'm thinking
about switching to the fi
