pynaunt allows you to deeply explore and introspect arbitrary python objects.

As an example, we can explore the os module just a bit:

>>> from pynaut import Container
>>> import os
>>> obj = Container(os)
>>> len(list(obj.children))
203
>>> w = list(obj.grep_attr_names('wait'))
>>> len(w)
23
>>> [a.name for a in w]
['wait',
  'wait4',
  'wait3',
  'wait',
  'wait4',
  'wait3',
  'waitpid',
  'wait',
  'wait4',
  'wait3',
  'waitpid',
  'wait',
  'wait4',
  'wait3',
  'wait',
  'wait4',
  'wait3',
  'waitpid',
  'waitpid',
  'waitpid',
  'waitget',
  'waitget',
  'waitget']
>>> from types import ModuleType
>>> test = lambda c: isinstance(c.obj, (bool, list, ModuleType))
>>> foo = list(obj.get_attr_matches(test))
>>> len(foo)
620
>>> [a.name for a in foo][:10]
['UserDict',
  'errno',
  'path',
  'auto_magic',
  'genericpath',
  'stat',
  'os',
  'UserDict',
  'errno',
  'path']

Additionally, there is support for searching an entire object tree for a (name, attribute) pair that meets an arbitrary condition.

pynaut also includes a very basic curses based interface (pynaut_curses) that lets you explore objects by descending through the attribute tree.
