(Re-sending to list instead of just to Alex.)
Alex,
Are you aware of these?
- try ... finally
- try ... except ... else
- continue
- break
- with
- @decorator
- x = a if b else c
-- Like the ternary operator a?b:c in other languages
- x = a or b
-- Assigns a, defaulting to b if a is false, unlike other
languages that might assign True or False
-- Short than the equivalent: x = a if a else b
Any other cool tricks out there, anyone?

Hey all,
I was looking at how to make my different jobs retry themselves, and found
the for-else construct. I know loops, comprehensions, ifs, and the like,
but I never knew for-else was available. Are there other constructs that I
may have missed--shortcuts or seemingly odd pairings of control statements
like this? Python has a lot of really cool shortcuts and features, like
get/hasattr, the yield keyword, or comprehensions. I always like finding
more to add to the toolbox.
