pydoc look up command (Emacs)

Just add the following stuff in your .emacs.
and type Ctrl-h f at point where you want to look up pydoc.

;;----pydoc lookup----
(defun hohe2-lookup-pydoc ()
(let ((curpoint (point)) (prepoint) (postpoint) (cmd))
(setq prepoint (buffer-substring (point) curpoint)))
(setq postpoint (buffer-substring (point) curpoint)))
(if (string-match "[_a-z][_\\.0-9a-z]*$" prepoint)
(setq cmd (substring prepoint (match-beginning 0) (match-end 0))))
(if (string-match "^[_0-9a-z]*" postpoint)
(setq cmd (concat cmd (substring postpoint (match-beginning 0) (match-end 0)))))
(if (string= cmd "") nil
(let ((max-mini-window-height 0))
(shell-command (concat "pydoc " cmd))))))

(add-hook 'python-mode-hook
(lambda ()
(local-set-key (kbd "C-h f") 'hohe2-lookup-pydoc)))

I had been thinking that Python is a toy and the rest of the programming languages are all tools, but I realized Emacs Lisp is a toy too. I'm sure I'm reinventing a wheel. Don't worry!
