  • Metaclasses in Python 1.5

    ...Python 1.5 Metaclasses in Python 1.5 (A.k.a. The Killer Joke :-) (Postscript: reading this essay is probably not the best way to understand the metaclass hook described here. See a message posted by Vladimir Marangozov which may give a gentler introduction to the matter. You may also want to search Deja News for messages with "metaclass" in the subject posted to comp.lang.python in July and August 1998.)

  • Python 2.4.1 - Linux RPMs

    ...Python? A. The RPMs that start with "python2.4" are built to not interfere with the system Python. They install as "/usr/bin/python2.4" and will not conflict with the system Python unless you are running on a system that ships the a version of Python which has the same major/minor number. To invoke the interpreter with these packages, you will explicitly have to run "python2.4". Note that all Python RPMs provided by Python.org and Red Hat provide a "/usr/bin/...

  • Unifying types and classes in Python 2.2

    ...Python ever, and yet it can be done with very few backwards incompatibilities. The changes are described in minute detail in a series of PEPs (Python Enhancement Proposals). PEPs are not designed to be tutorials, and the PEPs describing the type/class unification are sometimes hard to read. They also aren't finished yet. That's where this paper comes in: it introduces the key elements of the type/class unification for the average Python programmer. A bit of terminology: "classic Pyt...
