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.help(request)

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.
