In general, I think you should be more specific in the exceptions you
catch. For example, if you want to look up a key in a dictionary and most
of the time it's there, but every now and again you need to add it, I'd use
something like this:
try:
val = somedict[key]
except KeyError:
# need to initialize slot
somedict[key] = INITIAL_VALUE
That is, be as precise as you can in the exceptions you catch. Also, try to
keep the body of the try block as small as you can.
