• Unifying types and classes in Python 2.2

  ...classes are more accessible and less dangerous. Terminology-wise, a metaclass is simply "the class of a class". Any class whose instances are themselves classes, is a metaclass. When we talk about an instance that's not a class, the instance's metaclass is the class of its class: by definition, x's metaclass is x.__class__.__class__. But when we talk about a class C, we often refer to its metaclass when we mean C.__class__ (not C.__class__.__class__, which would be a meta-metaclass; th...

  ...center: all in one place, most people will stay there. It's more expensive than the Crowne ($135/night vs. $109 at the Crowne). We still have an obligation for rooms at Crowne, which is still the budget option. Also catering: we'll have one reception there, which will cover the $65K obligation. The bottom line is that we'll need some growth to meet the room obligation. There are two contracts to sign: RESOLVED, that the PyCon Chairman be authorized to sign the necessary contracts for PyCon 2...

• Notes

  ...classes of string can no longer be interned. The semantics of interning were not clear here -- a subclass could be mutable, for example -- and had bugs. Explicitly interning a subclass of string via intern() will raise a TypeError. Internal operations that attempt to intern a string subclass will have no effect. Bug 1003935: xrange() could report bogus OverflowErrors. Documented what xrange() intends, and repaired tests accordingly. Extension modules difflib now supports HTML side-by-si...

• Computer Programming for Everybody

  ...class" functions and classes pose significant challenges. We will also investigate program slicing [Tip] and program paths [Ball] as techniques to help users understand where to make changes and what impact those changes will have. Slicing is a well-known technique for identifying subsets of programs that affect a particular variable. Analysis via program paths shows the various possible execution paths through a body of code. Each technique has value for testing and debugging programs. T...

• Built-in Package Support in Python 1.5

  ...class or variable. The import statement first tests whether the item is defined in the package; if not, it assumes it is a module and attempts to load it. If it fails to find it, ImportError is raised. Contrarily, when using syntax like import item.subitem.subsubitem, each item except for the last must be a package; the last item can be a module or a package but can't be a class or function or variable defined in the previous item. Importing * From a Package; the __all__ Attribut...

This needs to be documented. The new builtin dictionary() constructor, and dic...
