> Here is an idea I've had for emacs python-mode: something

>
>  (defun string-rstrip (str)
>    "Strips the whitespace at the end of string STR."
>    (string-match "[ \t\n]*\\'" str)
>    (substring str 0 (match-beginning 0)))
>
>  (defun py-find-library (modname)
>    "Run a subordinate python to find out where a module is located
>  and load it in a buffer."
>    (interactive "MModule name: ")
>    (let* ((program (format "import %s as m; print m.__file__"  
> modname))
>           (filename
>            (replace-regexp-in-string
>             "\\(\\.pyc\\|\\.pyo\\)" ".py"
>             (string-rstrip
>              (shell-command-to-string (format "python -c '%s'"  
> program))))))
>      (unless (file-exists-p filename)
>        (error (format "File %s could not be found." filename)))
>      (find-file filename)
>      ))

> Feel free to scavenge, adapt and integrate in python-mode if
> you like.
