Show doc-string of function

I’m using the following settings in coc (from the coc README) to show documentation when pressing K:

" Use K to show documentation in preview window
nnoremap <silent> K :call <SID>show_documentation()<CR>

function! s:show_documentation()
  if (index(['vim','help'], &filetype) >= 0)
    execute 'h '.expand('<cword>')
  elseif (coc#rpc#ready())
    call CocActionAsync('doHover')
  else
    execute '!' . &keywordprg . " " . expand('<cword>')
  endif
endfunction

Previously I used coc-python which then showed the doc-string of the function. However with coc-pyright I’m just getting the signature of the function which in some cases is totally unusable. For example if I press K when on subprocess.run I get the monstrosity

@meandmymind I had a hack previously for earlier version of coc-python to get the correct python path for virtual environments. However, now I just set it back to:

    "python.pythonPath": "python",

and things worked
