Hi all,
I have the following problem:
There are strings describing a UTC time, e.g. " 2008-01-15 22:32:30"

What is an elegant way of getting the local time (considering DST -
daylight saving time) with that data?
The date is not important, just

You're still top posting and not trimming quotes. That annoys
a lot of people.

You have the order of a and b mixed up there. As you have it, you are
searching b for a.

I'd like "or" and "and" (and "not") to return booleans only, to avoid
bugs and make their meanin

I think the metaclass stuff is a bit too black magic for a pretty
simple requirement.
Txs in any case for showing me the __init__ issue, I wasn't aware of
it.
Here's a workaround - not exactly elegant in terms of OO, with the
isInitialized flag, but it works.
>>> class RDFObject(object):
...
I have type variable which may have been set to 'D' or 'E'
Now, which one of following statements are more efficient
if type =='D' or type == 'E':
or
if re.search("D|E", type):
Please let me know because the function is going to called 10s of millions
of times.
Thanks

Except that using has_key() means making an attribute lookup, which takes
time.
I'm kinda curious why you say they're "about the same" when your own
timing results contradict that. Here th

Do you think it is relatively easy to write sort algorithms such as
the common Bubble sort in Python as compared to other high level
programming langauges

I was going to say that, but doesn't 'in' require an attribute lookup of
some sort too, of __contains__ or whatever? has_key is probably now just
a wrapper around that, so it would be one mo
