Raymond Hettinger <[email protected]> added the comment:
The __missing__() method already fulfills this need:
class DoubleDict(dict):
def __missing__(self, key):
return key * 2
If desired, it can also add entries:
class DoubleDict(dict):
def __missing__(self, key):
self[key] = value = key * 2
return value
