But doing attentive googling will turn out a lot of 3rd-party blog
posts which discuss various implementation aspects of CPython (and even
alternative implementations). Some random links:

http://tech.blog.aknin.name/category/my-projects/pythons-innards/
http://eli.thegreenplace.net/2010/09/18/python-internals-symbol-tables-part-1/
http://nedbatchelder.com/blog/200804/the_structure_of_pyc_files.html

One should keep in mind that implementation evolves all the time, and
any info in older docs may be obsolete. So, the ultimate reference is
the source itself, but posts like above can be a good help to
understand it more easily and effectively.
