  • Unifying types and classes in Python 2.2

    ...problem in classic Python? Diamond diagrams are rarely found in classic Python class hierarchies. Most class hierarchies use single inheritance, and multiple inheritance is usually limited to mix-in classes. In fact, the problem shown here is probably the reason why multiple inheritance is unpopular in classic Python! Why will this be a problem in the new system? The 'object' type at the top of the type hierarchy defines a number of methods that can usefully be extended by subtypes...

We do not hold a trademark on these, but generally discourage use of these very old artifacts, simply in the interest of consistent branding. One older image that we sometimes encounter is specifically prohibited. Old logo/icon Problem Not protected by trademark, but simply a fairly archaic informal branding. Variation on the 1990s informal Python logo. Around 2005, Python wished to move from a &q...
