what is it
A Python package to parse and build CSS Cascading Style Sheets. (Not a
- refactored validation
- added Profiles. See the docs and source of the cssutils.profiles
module for details.
- should work on GAE now properly
- ``cssutils.resolveImports(sheet)`` returns a new stylesheet with
all rules in given sheet but with all @import rules being pulled into
the top sheet.
- CSSCombine script and helper function resolve nested imports now.
- ``csscombine`` has new option ``-u URL, --url=URL URL to
parse (path is ignored if URL given)`` now
- New documentation in Sphinx format
cssutils is published under the LGPL version 3 or later, see

Announcing : PLY-3.0 (Python Lex-Yacc)
I'm pleased to announce a significant new update to PLY---a 100% Python
implementation of the common parsing tools lex and yacc. PLY-3.0 adds
compatibility for Python 2.6 and 3.0, provides some new customization
options, and cleans up a lot of internal implementation details.
If you are new to PLY, here are a few highlights:
- PLY is closely modeled after traditional lex/yacc. If you know how
to use these or similar tools in other languages, you will find
PLY to be comparable.
- PLY provides very extensive error reporting and diagnostic
information to assist in parser construction. The original
implementation was developed for instructional purposes. As
a result, the system tries to identify the most common types
of errors made by novice users.
- PLY provides full support for empty productions, error recovery,
precedence rules, and ambiguous grammars.
- Parsing is based on LR-parsing which is fast, memory efficient,
better suited to large grammars, and which has a number of nice
properties when dealing with syntax errors and other parsing
problems. Currently, PLY can build its parsing tables using
either SLR or LALR(1) algorithms.
More information about PLY can be obtained on the PLY webpage at:
PLY is freely available and is licensed under the terms of the Lesser
GNU Public License (LGPL).

Webware for Python 1.0.1 has been released.
This is the first bugfix release for Webware for Python release 1.0,
mainly fixing a problem that could appear when communicating with the
threaded application server over a network connection. See the WebKit
release notes for details.
Webware for Python is a suite of Python packages and tools for
developing object-oriented, web-based applications. The suite uses well
known design patterns and includes a fast Application Server, Servlets,
Python Server Pages (PSP), Object-Relational Mapping, Task Scheduling,
Session Management, and many other features. Webware is very modular and
Webware for Python is well proven and platform-independent. It is
compatible with multiple web servers, database servers and operating

Chicago Python User Group
Go ChiPy! After last month's hugely successful language comparison
mayhem, the world's most successful user group strikes again!
Robots and OS Packaging, are the major topic areas.
James Snyder, from Northwestern University's Biomedical Engineering
Department, will be serializing Arduino microcontroller with Python
for robotic pursuits. Jason Huggins, co-founder of Sauce Labs Inc and
creator of Selenium, will follow up with a quick demo of his Arduino-
based Ambient Orb clone, called 'orbison' (http://code.google.com/p/orbison/
For the second part, Cosmin Stejerean, software engineering and
computer security specialist, will cover how to package your Python
package with tools like py2app and py2exe. Massimo Di Pierro,
professor at DePaul CTI, will get some brief help porting his popular
web2py Enterprise Web Framework to a linux package from a live
audience. Let's see if it is possible in 10 minutes!
Last but not least, William Scullin, Argonne National Laboratory and
cheese lover, will present on bcfg2, a tool written in Python for
system administrators to fingerprint their environment and about
Python, in general, on IBM's BlueGene /P supercompter.
There will be a moment of silence in respect to Unix Timestamp
Our host for the meeting is Sully's House Tap Room & Grill. All ages
are welcome to this Free Private Event. For those of age, Sully’s
House offer 20 Beers on tap, and 35 Bottles - all craft and
microbrewery, specializing in Belgium, Irish and German selections.
Enjoy great Bar Food & Pizza from our Italian Oven and Daily
discounted menu specials. The host has given us a dedicated
bartender. We will meet in the private party room on the second floor
that is well equipped with top of the line video equipment – 100” HD
screen & full A/V accessibility with Rock Band & Wii. Nice big space,
bring a friend. Thanks Sully's!!!
This *will* be our best meeting yet.
