Notes from PySIG, 24-May-2007: Python logging and wxPython

Thirteen participants made it to the May meeting of the Python Special Interest Group of the Greater New Hampshire Linux User Group, held as usual on the fourth Thursday of the month at 7 PM at the Amoskeag Business Incubator, Manchester, NH.

It was a busy meeting. A quick round of introductions and announcements was followed by several terrific presentations.

Kent Johnson entertained us with Kent’s Korner, this month featuring the logging module. Simple logging can be implemented in two lines of code and customized with a third, but the module can be expanded almost infinitely to include multiple handlers arranged in a hierarchical fashion with different levels of filtering and multiple output. As usual, Kent did a fine job of showing simple examples and clearly building on them.

Bill Sconce decided to defer his second attempt at describing a hierarchy of data types, a discussion sure to rouse an interesting and educational debate amongst the participants. Stay tuned for a future meeting…

Ric Werme made the main presentation on wxPython. He brought the most extensive handouts we’ve had today, with an engaging backstory of his several-decades tinkering with graphing and the Petals of the Rose patterns. The demo was arresting, and source code can be downloaded here and here. Ric walked us through the wxPython wrapper, explaining the various widgets used and spoke well of the new wxPython book.

Thanks to Ric and Kent for their presentations, to Bill Sconce and Alex Hewitt for arranging the meeting and facilities, to the Amoskeag Business Incubator for their hospitality and to all who attended for their participation!
