Cameron Laird's personal notes on varieties of Python implementation
I started this page in 1998. Finally in 2007 I began to
move its content to the
Wiki; look there for the latest information. Until
the transition is complete, what follows was, at least,
correct at one time:
Multiple implementations process the Python
computer language. Those coming from
Java, C, FORTRAN, and
so on might find this unremarkable; it's a striking contrast,
though, with Python's most immediate peers:
... Eventually I'll analyze the dynamics of this phenomenon.
In the meantime, I intend to catalogue the diversity:
quality-assured binary build ..."
- "berp is an implementation of Python 3, written in Haskell."
- CPython is Guido
reference Python [mention version prospects]
- deeply embedded
the unholy extent of supporting the ZODB Webscale Edition
offers even more "batteries" than usual, including
packages for GUI construction, scientific programming,
persistence, visualization, and more.
("It's not full Python but it's
close", in the words of one colleague)
is interesting enough to deserve an entire article of its
own. I hope to write it in 2004 [also be aware of the related

earlier independent experiments, he's now folded his
efforts on top of
Stackless. As of
Day 2000, task
switching is not yet pre-emptive. Stackless 1.1 includes
a per-thread scheduling hook that simplifies this fix.
Warren Postma and other control programmers like the
microthreads project for the constraints it should give
on thread latency.

of particular interest to me, is "slenderized"

Lloyd and others have worked on tinyPython. One approach is

work for me";

Python, created by Mark Dufour."
