It fails also for builtin "type". $ ./python -m pydoc type Traceback (most recent call last): File "/home/serhiy/py/cpython/Lib/runpy.py", line 192, in _run_module_as_main return _run_code(code, main_globals, None, File "/home/serhiy/py/cpython/Lib/runpy.py", line 85, in _run_code exec(code, run_globals) File "/home/serhiy/py/cpython/Lib/pydoc.py", line 2765, in <module> cli() File "/home/serhiy/py/cpython/Lib/pydoc.py", line 2727, in cli help.help(arg) File "/home/serhiy/py/cpython/Lib/pydoc.py", line 1967, in help elif request: doc(request, 'Help on %s:', output=self._output) File "/home/serhiy/py/cpython/Lib/pydoc.py", line 1690, in doc pager(render_doc(thing, title, forceload)) File "/home/serhiy/py/cpython/Lib/pydoc.py", line 1683, in render_doc return title % desc + '\n\n' + renderer.document(object, name) File "/home/serhiy/py/cpython/Lib/pydoc.py", line 386, in document if inspect.isclass(object): return self.docclass(*args) File "/home/serhiy/py/cpython/Lib/pydoc.py", line 1258, in docclass (str(cls.__name__) for cls in object.__subclasses__() TypeError: descriptor '__subclasses__' of 'type' object needs an argument |

There are two ways of solving this issue: 1) skip this chunk of code if object is a type subclass, 2) use `type.__subclasses__(object)` instead of `object.__subclasses__()`. |
