  • Computer Programming for Everybody

    Computer Programming for Everybody Computer Programming for Everybody This is the main text of a funding proposal that we sent to DARPA in January 1999. In August 1999, we submitted a revised version of the proposal. Please look at the EDU-SIG home page (Python in Education Special Interest Group). This is where the current project status is described and/or will be discussed, and where you'll find pointers to more resources. Note:I have made one change to the text of the propos...

The standard test program test_compiler was one such program. If a Python process on Windows "just vanishes" without a trace, and without an error message of any kind, but with an exit code of 128, undetected stack overflow may be the problem.

    Metaclasses in 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.) In previous Python releases (and still in 1.5), there ...

  • What's new in Python 2.3

    ....3. Faster According to a couple of simple benchmark, Python 2.3 is about 20-30% faster than Python 2.2.3. Some of this speed-up was obtained by removing the SET_LINENO opcodes, which means that the difference is less impressive when comparing "python -O"; the rest was various careful tune-ups. New Tools A brand new version of IDLE (from the IDLEfork project at SourceForge) is now included as Lib/idlelib. The old Tools/idle is no more. New or upgraded built-ins sum() - a new f...

  • Built-in Package Support in Python 1.5

    Built-in Package Support in Python 1.5 Built-in Package Support in Python 1.5 Starting with Python version 1.5a4, package support is built into the Python interpreter. This implements a slightly simplified and modified version of the package import semantics pioneered by the "ni" module. "Package import" is a method to structure Python's module namespace by using "dotted module names". For example, the module name A.B designates a submodule named B in a package named A. Just like...

  • Unifying types and classes in Python 2.2

    ....3. C3 is monotonic just like the book's algorithm, but in addition maintains the order of the immediate base classes, which the book's algorithm doesn't always do. A very accessible description of C3 for Python is The Python 2.3 Method Resolution Order by Michele Simionato. The book outlaws classes containing such order disagreements, if the order disagreement is "serious". An order disagreement between two classes is serious when the two classes define at least one method with th...
