help CLI shows a traceback when import failed #102541
Description
Currently, help will show a traceback when we type name of something which doesn't exist:
help> 123 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<frozen _sitebuiltins>", line 103, in __call__ File "C:\Users\KIRILL-1\CLionProjects\cpython\Lib\pydoc.py", line 2004, in __call__ self.interact() File "C:\Users\KIRILL-1\CLionProjects\cpython\Lib\pydoc.py", line 2031, in interact self.help(request) File "C:\Users\KIRILL-1\CLionProjects\cpython\Lib\pydoc.py", line 2057, in help elif request: doc(request, 'Help on %s:', output=self._output) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\KIRILL-1\CLionProjects\cpython\Lib\pydoc.py", line 1781, in doc pager(render_doc(thing, title, forceload)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\KIRILL-1\CLionProjects\cpython\Lib\pydoc.py", line 1755, in render_doc object, name = resolve(thing, forceload) ^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\KIRILL-1\CLionProjects\cpython\Lib\pydoc.py", line 1741, in resolve raise ImportError('''\ ImportError: No Python documentation found for '123'. Use help() to get the interactive help utility. Use help(str) for help on the str class. >>>I think, this shouldn't be shown.
Is there any reason for this?
Can we show something like
No python documentation found for '123'.?
Reproducible on current main.
