I would like to be able to do something along the lines of:
>>> my_list = [1, 2, x for x in range(3,6), 6]
However this doesn't work. Is there any way of achieving this kind of thing?
I tried:

which also doesn't work.

Is there a particular way to force a value to be an int by either
converting it with int() or returning a default value.
I've ended up writing my own function to do it, but it seems like the
kind of thing that would be built-in somewhere.

I seem to have a lot of questions today. Sorry.
How can I convert a string in the format "%Y-%m-%d %H:%M:%S" into a
datetime object?
I can work out how to convert it to a time object by:
import time
timestring = "2005-09-01 12:30:09"
time_format = "%Y-%m-%d %H:%M:%S"
mytime = time.strptime(time
s when you
don't know what they're called is a bit of a stumbling block
sometimes.
Maybe a page that very briefly summarises the 'unsearchable' with
links to fuller descriptions?

I'd like a little advice on whether I'm being really stupid here.
Having researched editors and stuff, I've not quite found what I'm
looking for, though Vim comes close (except that it's extremely
difficult to work out what to do with it).
My instinct was to try and write a small program similar
the word you're typing based on what you've already written
in the file.
I've also been trying SPE and that looks to be the most pleasing
editor so far. It's also written in Python (AFAICT) which will
probably have benefits in the future.
