Dr. Dobb's Python-URL! - weekly Python news and links (May 31)

QOTW: "Not tested but confident should be an oxymoron for a
programmer." - Peter Otten

(Asked "Is this unsurprising if I look at it right?") - "Yes; in

Fuzzyman tells us how to build a Movable Python CD - that is, Python
that you can run straight off the CD without any installation - with
a custom set of packages:

Why is Python case-sensitive? Because mathematical notation is,
apparently:

Mark Williamson has difficulty generating API documentation. Python
still needs a javadoc analogue that doesn't import code, it seems:

Gabor would like to be able to write to a single text file from
multiple processes simultaneously. This is hard.

Eval is unsafe at any speed. Duncan Booth takes on all comers and
