That's a great list, grflanagan! Thanks. I looked at each and copied to my disk either as a .txt (cut/paste from the browser) for a page or less or as .html (view source, chop off head and non-guideline stuff, save). This is the list plus PEP 8 minus the software. (No disrespect for the software, just sticking to written standards.) Zope may be a substantial guideline, but it linked to a page of Zope links, all of which were broken.
This CSV file is sorted by filesize on my disk. One presumes that a relationship exists between size and extent of coverage. (Warning: Wiki text could be as much as twice the size of non-wiki for the same content.) The third column is empty (spacer between size and URL). A quick look (thorough analysis still required) shows that OLPC and PyPy are, indeed, extensive standards. one-laptop-per-child.html (olpc),74.3,,http://wiki.laptop.org/go/ Python_Style_Guide pypy.html,64.2,,http://codespeak.net/pypy/dist/pypy/doc/coding- guide.html pep-008.html,35.6,,http://www.python.org/dev/peps/pep-0008/ knight.html,33.7,,http://jaynes.colorado.edu/PythonGuidelines.html pep-257.html,23.8,,http://www.python.org/dev/peps/pep-0257/ webware.html,23.4,,http://www.webwareforpython.org/Docs/ StyleGuidelines.html twisted.html,23.3,,http://twistedmatrix.com/trac/browser/trunk/doc/ development/policy/co... voice-code.html,17.9,,http://voicecode.iit.nrc.ca/VoiceCode/uploads/ codingGuidelines.html fsl.html,15.0,,http://www-md.fsl.noaa.gov/eft/developer/ PythonCodingStandards.html wx.html,14.6,,http://www.wxpython.org/codeguidelines.php mnet.html,14.5,,http://mnet.sourceforge.net/coding_standards.html michael-foord.html,14.2,,http://www.voidspace.org.uk/python/weblog/ arch_d7_2006_04_01.shtml#e296 bazaar.html,10.4,,http://doc.bazaar-vcs.org/bzr.dev/en/developer-guide/ HACKING.html#cod... ipython.html,10.2,,http://ipython.scipy.org/moin/Developer_Zone/ Developer_Guidelines barry-warsaw.html,6.2,,http://barry.warsaw.us/software/STYLEGUIDE.txt django.html,5.6,,http://www.djangoproject.com/documentation/ contributing/#coding-style chandler.txt,4.0,,http://chandlerproject.org/Projects/ ChandlerCodingStyleGuidelines pyblosxom.txt,3.8,,http://pyblosxom.sourceforge.net/blog/static/ development#coding freevo.txt,3.4,,http://jaynes.colorado.edu/PythonGuidelines.html sql-object.txt,2.7,,http://www.sqlobject.org/DeveloperGuide.html#style- guide biopython.txt,2.5,,http://biopython.org/wiki/ Contributing#Coding_conventions tracdev.txt,1.8,,http://trac.edgewall.org/wiki/TracDev/CodingStyle docutils,1.8,,http://docutils.sourceforge.net/docs/dev/ policies.html#python-coding-... moinmoin.txt,1.8,,http://moinmoin.wikiwikiweb.de/CodingStyle cherrypy.txt,1.5,,http://www.cherrypy.org/wiki/CodeConventions skeletonz-naming.txt,1.4,,http://orangoo.com/skeletonz/Developer_guide/ Naming_convention/ mercurial.txt,0.9,,http://www.selenic.com/mercurial/wiki/index.cgi/ Basic_Coding_Style skeletonz-coding.txt,0.6,,http://orangoo.com/skeletonz/Developer_guide/ Coding_convention/ software-carpentry.txt,0.1,,http://www.swc.scipy.org/lec/style.html zope.txt,0.0,,http://wiki.zope.org/zope3/CodingStyle -- http://mail.python.org/mailman/listinfo/python-list
