R. David Murray added the comment: It would not be sensible for pop to return the default value, since the point of pop is to *remove* a key from the dictionary (while returning the existing value), whereas the point defaultdict is to *add* key to the dictionary with the default value if you retrieve a non-existent key. As Martin said, an important aspect of defaultdict is that *only* getattr has this default behavior; things like 'in' still work like a regular dictionary with a defaultdict.
