| current dir gives output like this, ``` from collection import OrderedDict od = OrderedDict({'a': 1, 'b': 2, 'c': 3}) print(dir(od)) ``` ``` ['__class__', '__contains__', '__delattr__', '__delitem__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__subclasshook__', 'clear', 'copy', 'fromkeys', 'get', 'items', 'keys', 'move_to_end', 'pop', 'popitem', 'setdefault', 'update', 'values'] ``` but wouldn't it be better if the output was like this, ``` {'OrderedDict': {'__contains__', '__delitem__', '__dir__', '__eq__', '__format__', '__ge__', '__getitem__', '__gt__', '__init__', '__init_subclass__', '__iter__', '__le__', '__lt__', '__ne__', '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__setitem__', '__sizeof__', '__subclasshook__', 'clear', 'copy', 'fromkeys', 'get', 'items', 'keys', 'move_to_end', 'pop', 'popitem', 'setdefault', 'update', 'values'}, 'dict': {'__getattribute__', '__len__', '__new__'}, 'object': {'__delattr__', '__setattr__', '__str__'}} ``` ??? |

| This would be nice, but backward compatibility alone means we can't change dir() to return a dictionary. What you propose would make more sense as a new function, perhaps in a package like pydoc or a third-party tool like IPython. |

| would adding an argument to dir be a possible solution, like, ``` l = [1, 2, 3] dir(l, categorize=True) ``` |

| plus I would want it to have some more methods, ``` l = [1, 2, 3] ``` using enhanced dir should give, ``` {'list': {'__add__', '__contains__', '__delitem__', '__eq__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__iadd__', '__imul__', '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__repr__', '__reversed__', '__rmul__', '__setitem__', '__sizeof__', '__subclasshook__', 'append', 'clear', 'copy', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort'}, 'object': {'__delattr__', '__dir__', '__format__', '__reduce__', '__reduce_ex__', '__setattr__', '__str__'}} ``` obtained from, (here only printing, made a dictionary in the implementation in the PR) ``` for j in dir(l): print(f'l.{j}.__qualname__') ``` this check fails for, ``` {'list': {'__doc__', '__hash__', '__class__'}} ``` I would also want these, ``` {'list': {'__instancecheck__','__subclasscheck__', '__subclasses__', 'mro'}, 'type': {'__call__', '__prepare__'}} ``` which were obtained from, ``` for j in set(dir(type(l))) - set(dir(l)): print(f'l.{j}.__qualname__') ``` and it fails for, ``` {'list': {'__abstractmethods__', '__base__', '__bases__', '__basicsize__', '__dict__', '__dictoffset__', '__flags__', '__itemsize__', '__module__', '__mro__', '__name__', '__qualname__', '__text_signature__', '__weakrefoffset__'} ``` |
