Nicely done. I seldom hack in python (usually only when I need to tweak a tool to add/fix a feature), so I don't know it or its libraries very well. Still, after googling itertools and finding that the module is implemented in C, I'm confident your solution is as fast as it gets using python.

I also came across some python code that's very similar to what I wrote earlier, heh.
http://docs.python.org/library/itert...s.combinations

Amusingly, I just tried to time the itertools approach on my machine, but since the only python I have installed is 2.5.1 (it's not my main machine), itertools is not available (it's new in 2.6). It's an old OSX Tiger macbook that I don't use much.

Alister

PYTHON-COVERAGE(1)					      General Commands Manual						PYTHON-COVERAGE(1)

NAME
python-coverage - measure code coverage of Python program execution SYNOPSIS
python-coverage -x module.py [ARG...] python-coverage -e python-coverage -r [-m] python-coverage -a [file...] DESCRIPTION
python-coverage executes a Python program and measures which of its statements are executed and which are not. It stores the information in the file .coverage in the current working directory. OPTIONS
-e Erase the .coverage file. -x Execute a Python module, giving it the remaining command line arguments. -r Produce a coverage report. -m With -r, show the line numbers that were missed by the execution. -a Annotate source files. For each source file foo, produce foo,cover, with executed lines prefixed by ">" and non-executed by "!". --help Produce a help summary. It might be more helpful than this manual page. AUTHOR
The python-coverage command is a one-line Python script which calls the coverage.py Python module to do all the work. The module was rigi- nally developed by Gareth Rees, and is now developed by Ned Batchelder. The module's home page is http://www.nedbatchelder.com/code/modules/coverage.html. This manual page was cobbled together by Lars Wirzenius for Debian, by copy-pasting from the help texts from the module. PYTHON-COVERAGE(1)
