Looking at the docs for warnings.simplefilter
(http://docs.python.org/2/library/warnings.html) I think the following
script should only produce one warning at each line as any message is
matched by the simple filter
import warnings
warnings.simplefilter('default')
for i in xrange(2):
warnings.

Hi,
I was hoping namedtuples could be used as replacements for tuples in all
instances. There seem to be some differences between how tuples and namedtuples
are created. For example with a tuple I can do:
a=tuple([1,2,3])
with namedtuples I get a TypeError:
from collections import namedtuple

Seems to me that 'while not done:' is no better than
'while True:', because in both cases you have to look
inside the loop to find out what the exit condition

I tried listings. I believe pygments makes better formatted output (at
