it's actually fairly common to deal with KeyError instead of using
dict.get or w/e.
When doing that, though, it's good practice to make sure the
try/except encloses the minimum amount of code needed.
E.g. instead of
try:
value = somedict[get_my_key()]
except KeyError:
value = something_else()
it's better to write
k = get_my_key()
try:
value = somedict[k]
except KeyError:
value = something_else()
Then there's no chance of accidentally swallowing a KeyError
produced by get_my_key().
