For the record, the four lines Paul implies are "confusing" are:

Consider what happens if the computation of "key" or "value" itself
raises KeyError.
Isn't key and value just a simple variables/names? Why should it ever
raises KeyError? The only other error that try-block code could ever
possibly throw are NameError and possibly MemoryError.
