Dr. Dobb's Python-URL! - weekly Python news and links (Sep 22)

[Raymond Hettinger]

QOTW:  "Python seems to encourage and reward incremental effort, and it leads
one to explore extensions and improvements to programs because the language
makes it relatively easy to see how to do the extensions."  -- Ron Stephens

"When writing programs in Python, write Python programs" -- Jeff Epler's
advice to those forcing themselves to write code using idioms learned in
other languages

"Oh come on, now, just because Java does it..."  -- Dave Benjamin's snappy
comeback to Bob Grailer's facetiously offered name for an inverse yield
statement called "suck".

Everything Python-related you want is probably one or two clicks away in
these pages:

    are utterly different in their technologies and generally in
    their results.
