It would be useful if there was some direct way to get the value
associated with a key, and None if there's not one.
The basic options are
if dict.has_key(key} :
value = dict[key]
else :
value = None
or
try:
value = dict[key]
except:
value = None
one of which requires two lookups, and the other of which takes
you through the exception machinery.
This can be a bottleneck in some text processing applications.
But it's not a big deal.
