well, I'm totally undisciplined, and I just love

if you find yourself using a lot of "x = x + 1" in your
code, you're probably not using for-in and other
sequence operations as much as you should...

if list contains 3-tuples, that works exactly as you'd
expect.  if you have three lists, you can do:

    for x, y, z in map(None, list1, list2, list3):

a better syntax for this might make it into 1.6 (at least
according to GvR's presentation on the last python con-

here are a few ways to do that:

    "%d" % integer

what's a "regular array construct", and how does that
differ from a python list?

(if you mean multidimensional arrays, numerical python
has that -- and those parts of numpy is very likely to
make it into standard python any day soon...)

yeah, but regular expression syntax suck ;-)

    Some people, when confronted with a problem, think
    "I know, I'll use regular expressions".  Now they have
    two problems.

(I hope Python will grow a much cooler string pattern
syntax some day, but that's another story.)

with a little performance tuning, and some additional
widgets, Tkinter is quite ok (but I might be biased...)
