according doc of types module (http://docs.python.org/py3k/library/types.html),

this module defines names object types used standard python interpreter, not exposed builtins int or str are. ...

typical use isinstance() or issubclass() checks.

since dictionary type can used dict, there no need introduce such type in module.

>>> isinstance({}, dict) true >>> isinstance('', str) true >>> isinstance({}, str) false >>> isinstance('', dict) false 

(the examples on int , str outdated too.)
