Kent's Korner:
Context managers and the 'with' statement
"A common need in programming is to guarantee some kind of cleanup
after a block of code is run; for example, closing a file or
database connection after use. The usual way to do this in Python
prior to version 2.5 is with a try / except block..."
[There's a better way, much more robust, and what's really
important, easier. -ed]
Plus:
-------------------------------------------------------------------
o Our usual roundtable of introductions, happenings, announcements
o Data Types VIII
- (Running PySIG joke :)
o Gotcha contest
- Got a favorite "gotcha"? Bring it and share...
And of course, milk, & cookies.
This month: Oatmeal, with and w/o chocolate (you know who you are)

About PySIG:
PySIG meetings are typically 10-20 people, around a large table
equipped with a projector and Internet hookups (wired and
wireless). We encourage laptops and a hands-on seminar style.
The main meeting starts at 7 PM; officially we finish circa 9 PM.
Everyone is welcome. ("Membership" is anyone who has an interest
in the Python progamming language, whether on Microsoft systems
or Linux or OS X; or cell phones, mainframes, or space stations.
We have everyone from object-oriented gurus to recovering COBOL
programmers.) Tell your friends!
Beginners' session:
The half hour before the formal meeting (i.e., starting at 6:30PM)
we have a beginners' session. Any Python question is welcome --
whoever asks the first question gets the half hour! Questions are
equally welcome by mail beforehand (in which case we can announce
them) or at the meeting. (As are all Python questions, anytime.)

About Python:
"Python is a dynamic object-oriented programming language that
can be used for many kinds of software development. It offers
strong support for integration with other languages and tools,
comes with extensive standard libraries, and can be learned
in a few days. Many Python programmers report substantial
productivity gains and feel the language encourages the
development of higher quality, more maintainable code."
"NASA uses Python...so does Rackspace, Industrial Light&Magic,
AstraZeneca, Honeywell, and many others."
Google: "Python has been an important part of Google since the
beginning, and remains so as the system grows and evolves."
-Peter Norvig
