When using Vim to write Python programs under Linux, can "query the help content of Python, that is, Python-doc" be done like "vim-doc"?

Question

[Description]
For example, to view a certain help content of Vim, you can :h help-content. Is it possible to do this when viewing Python-doc?
(I am now viewing Python The help content is all viewed in IPythonhelp-content?, but this requires opening another shell window)

"python help"
nnoremap  K :let save_isk = &iskeyword \|
    \ set iskeyword+=. \|
    \ execute "!pydoc " . expand("") \|
    \ let &iskeyword = save_isk

This is what I use under window. For Linux, the modification should not be big, you can try it.

The key is pydocthe issue of commands.
