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
general this is true across many domains for a very large number of
referents of "it" :-)" - John Machin

"Strong typing means there [are] a lot of variables whose names are
in ALL CAPS." - Paul Rubin


One common Python "gotcha" is that default argument values are
only evaluated once, at function definition time. David Isaac
wanted to know where the values are stored:

A new era in Python package management?

Markus would like to limit his Python script to a fixed percentage of
CPU usage:

How do you drive-by-wire a car using Python? The Pegasus Team is
doing some very cool stuff with Python - but I'd want to see their
test results before going within a mile of the thing.

Michael Smith wanted to check poker-dice rolls to see if they were a
full house. Raymond Hettinger gives him general purpose card hand
detection code:

George asks for help with a regexp to do quoted string parsing, then
is shown the light, and uses PyParsing instead.

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
shows that you can do dangerous things with eval regardless of
attempts to make it safe:
