Hm, replacing the return with a random string, this leads to another crash: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/ilevkivskyi/src/cpython/Lib/_sitebuiltins.py", line 103, in __call__ return pydoc.help(*args, **kwds) File "/Users/ilevkivskyi/src/cpython/Lib/pydoc.py", line 1895, in __call__ self.help(request) File "/Users/ilevkivskyi/src/cpython/Lib/pydoc.py", line 1954, in help else: doc(request, 'Help on %s:', output=self._output) File "/Users/ilevkivskyi/src/cpython/Lib/pydoc.py", line 1674, in doc pager(render_doc(thing, title, forceload)) File "/Users/ilevkivskyi/src/cpython/Lib/pydoc.py", line 1667, in render_doc return title % desc + '\n\n' + renderer.document(object, name) File "/Users/ilevkivskyi/src/cpython/Lib/pydoc.py", line 385, in document if inspect.ismodule(object): return self.docmodule(*args) File "/Users/ilevkivskyi/src/cpython/Lib/pydoc.py", line 1157, in docmodule for importer, modname, ispkg in pkgutil.iter_modules(object.__path__): File "/Users/ilevkivskyi/src/cpython/Lib/pkgutil.py", line 123, in iter_modules raise ValueError("path must be None or list of paths to look for " ValueError: path must be None or list of paths to look for modules in The reason is that `__getattr__` is also triggered when a special attribute is looked up. I am not sure what to do with this. This is a bit inconsistent with how classes behave, where e.g. `__len__` is never searched on an instance. But modules are special in many other ways, so maybe we can just fix pydoc (and other tools like inspect) to expect some ill-typed values in special module attributes and fail gracefully? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33668> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
