About Python Module of the Week
PyMOTW is a series of blog posts written by Doug Hellmann. It was started as a way to build the habit of writing something on a regular basis. The focus of the series is building a set of example code for the modules in the Python standard library.
Complete documentation for the standard library can be found on the Python web site at http://docs.python.org/library/contents.html.
Translations and Other Versions
Ralf Schönian is translating PyMOTW into German, following an alphabetical order. The results are available on his web site, http://schoenian-online.de/pymotw.html. Ralf is an active member of the pyCologne user group in Germany and author of pyVoc, the open source English/German vocabulary trainer (http://code.google.com/p/pyvoc/).
Roberto Pauletto is working on an Italian translation at http://robyp.x10hosting.com/. Roberto creates Windows applications with C# by day, and tinkers with Linux and Python at home. He has recently moved to Python from Perl for all of his system-administration scripting.
Ernesto Rico Schmidt provides a Spanish translation that follows the English version posts. Ernesto is in Bolivia, and is translating these examples as a way to contribute to the members of the Bolivian Free Software community who use Python. The full list of articles available in Spanish can be found at http://denklab.org/articles/category/pymotw/, and there is an RSS feed.
Tetsuya Morimoto is creating a Japanese translation. Tetsuya has used Python for 1.5 years. He has as experience at a Linux Distributor using Python with yum, anaconda, and rpm-tools while building RPM packages. Now, he uses it to make useful tools for himself, and is interested in application frameworks such as Django, mercurial and wxPython. Tetsuya is a member of Python Japan User’s Group and Python Code Reading. The home page for his translation is http://d.hatena.ne.jp/t2y-1979/20090525/1243227350.
Gerard Flanagan is working on a “Python compendium” called The Hazel Tree. He is converting a collection of old and new of Python-related reference material into reStructuredText and then building a single searchable repository from the results. I am very pleased to have PyMOTW included with works from authors like Mark Pilgrim, Fredrik Lundh, Andrew Kuchling, and a growing list of others.
Thank you to John Benediktsson for the original HTML-to-reST conversion.
