First, I second Matt's comment about using a boring old for loop when
it is the simplest way to express what you want to do. Being Pythonic
is not about using exotic features to scrunch your code down to a cool
one-liner. It is about expressing your intentions in a simple, direct
way. Sometimes

The most widely used such language would probably be COBOL,

Is there any legal problem with including licenses for languages you

worthy of concern will figure it out in short order if they care.)

Since you are getting the regular expression pattern via an argument I
would first check that searchPattern is what you expect. Shells can do
funny things with arguments containing special characters. Also, is
it possible that the quoted strings in the files contain escapes? For

The following program gets a TextCtrl's text attributes and sets them
back unchanged. However it reports that the font size is 124, and after
resetting the attributes the text becomes that size. That is, the
window displays a normal-size "foo" and a gigantic "bar". Anyone know
what's going on?

For your example, since the probabilities are all multiples of 0.01 you
could make a list of 100 elements. Set one of them to a, 5 of them to
b, 50 of them to c, etc. Then just randomly sample from the table

Seem to be a lot of regular expression questions lately. There is a
neat little RE demonstrator buried down in
Python24/Tools/Scripts/redemo.py, which makes it easy to experiment
with regular expressions and immediately see the effect of changes. It

The basic problem is that the zipfile interface only reads and writes
whole files, so it may perform poorly or fail on huge files. At one
time I implemented a patch to allow reading files in chunks. However I
believe that the current interface has too many problems to solve by
incremental patching,
If I were you I would see if I could get the Perl script referred to on
the ERIN web page. You might find that the discrepancy is something as
simple as a slightly different value for the Earth's radius. And by the
way, math.radians() might be a bit clearer than the pi/180 business.

Is this guaranteed by the Python specification, or is it an artifact of
