Have Guido and Dan been practicing their aim with a pie? The topic of the Python/Parrot shootout hasn't come up in awhile. I thought I'd ask since OSCON 2K4 is only a couple weeks away. Skip

An outdated weblog entry I wrote: http://www.amk.ca/diary/archives/cat_python.html#003176. I'll try to write another update once I actually get it to run Python code. Serious development activity in Parrot CVS started a few days before the end of June. At this point there are a few basic data types (string, int, float, lists, complex), a subset of the built-in functions (divmod, hex, chr, etc. -- map/filter/reduce are the most complicated ones implemented), and exceptions work to some degree. It can run a version of the pi() function in b0.py that's been rewritten to not use yield. Single-parent classes are being implemented at this point, but it's not clear whether they work at all; ask again in a few days. Can they finish within the time available? I'm not sure; Python is a relatively small language but it's not *that* small, and there's still a lot left to do. The approach being taken is translating the bytecode; there's a languages/python/piethon.pl script that takes a .pyc and produces a Parrot assembly file. There's some subtlety to invoking it, though, because the PASM produced doesn't actually assemble for me. I haven't yet figured out how to run a snippet of Python code using Parrot, so this assessment comes from looking at the code. (This means I obviously don't have any performance numbers either.) I forget the terms of the bet; is it running on Python 2.3.4, or the 2.4alpha1 release, or on Python CVS? Maybe we should check that 2.4CVS hasn't regressed in performance when compared to 2.3. --amk

Maybe we should check that
2.4CVS hasn't regressed in performance when compared to 2.3.
Test results on my machine comparing Py2.4a1 vs Py2.3.4: Parrotbench runs 10% faster on Py2.4a1 PyBench runs 11% faster on Py2.4a1 PyStone runs 6% faster on Py2.4a1 test_decimal.py runs 7% faster on Py2.4a1 My personal apps run 8 to 17% faster on Py2.4a1 without using new features. These tests gain 2-4% if profiling of C functions is disabled for an apples to apples comparison to Py2.3 which doesn't profile C functions. Raymond

Last week I've answered a few emails from Dan's minion who is responsible for the actual Python port, and Kevin Altis found us an impartial judge. So I better start practice my throwing, and Dan better start practice his ducking. ;-) --Guido van Rossum (home page: http://www.python.org/~guido/)

Whatever's in CVS for 2.4. --Guido van Rossum (home page: http://www.python.org/~guido/)

Shouldn't you do practice sessions?
I would have loved to volunteer, but I won't be at OSCON. But maybe we
could take a vote as to which python-dev member we would really like to
see as your sparring partner:-)
