Hi all,
What's the best way to pull arrays from a database for plotting?
Right now, this is what I do, but can it be done simpler / more
efficiently?
ipython -pylab
import sqlite3
cx = sqlite3.connect('20080407.decimated.db3')
a = array( [tuple(row) for row in cx.execute('SELECT cg_offset,
delta_
Jean-Michel,
Thanks for the excellent response setting me straight. Now to figure
out what dumb thing I did to make my code not work...

I'm trying to build an OO system for encoding and decoding
datapackets. I'd like the parent class to have an encode function
that uses each of the child classes' packing methods. It appears that
this works for attributes of children accessed by the parent, but not
for methods. Is that right? Fo

Thanks Dennis, The desciription works, but gives some funky results,
but with python it is not a big deal.

Perfect. Thanks much!

Thanks Tim! That works well. As a followup, is there a standard
compliant way to ask what fields are in the table?

Hi All,
I have some old pysqlite 1.x code that uses a pattern like this:
cu.execute('SELECT weight FROM weights WHERE samplename="foo")
row = cu.fetchone()
weight=row['weight']
It seems like lookups by name are no longer supported in pysqlite2. Is
that true? And if not, and I want to do a SELE
Hi Dieter,
Thanks for the feedback. Were you also using mac osx? I am wondering
at what level this bug is occuring.

Hi All,
I've tried to RTFM this and am having no luck.First off, I am using
Mac OSX 10.4.7 with python 2.4.2 from fink. I am trying to connect to
a server that should be rejecting connections and I was surprised when
it did not throw an exception or do something otherwise equally nasty.

Awesome. Thanks!

Hi All,
This is probably a FAQ, but is there an operator mapping for += for
classes? Or does a += b get converted to a = a + b? I would like to
make this operator faster for the BitVector class, but I don't see +=
in http://docs.python.org/lib/operator-map.html
I could always create an append m

I am creating a python package that contains a whole pile of functions

Hi All,
I was wondering if there is a helper library out there that will nicely
encode artibrary text so that I can put in into a TEXT field in a
database and then retrieve it without getting into trouble with ',",new

Awesome!!! When did doxygen start supporting python? I was really

Done any one have a way (and examples) of how to do math markups in the
docstrings of function and class definitions such that the equations
get typeset in the generated html documentation? I'll take any markup
system that'll do the job... MathML or LaTeX possible?
I'd like to start doing a bette
Hi All,
Is there an easy way to keep the unittest stuff out of the
documentation that gets generated by pydoc -w? I just want to exclude
the "Methods inherited from unittest.TestCase:" section.

Hi All,
Does anyone have a good template that I might use for writing a python
paper in latex/bibtex? I've got the paper mostly done, but am having
issues with the references. I am definitely not an expert at
latex/bibtex. Right now, I have references defined like this:
