Emacs: Go to first Python import statement

I was looking at PerlySense briefly because I occasionally have to do some Perl at work, along w/ Python, shell, Java & C++. The latter 2 are fairly infrequent, but still, Emacs makes such a heterogeneous work place alot easier. PerlySense has a keyboard shortcut that will take you to the "use module" section of a script/module. I wanted to do something similar in Python that would take you to the first "import module" section in a Python script/module. I love the dynamic programming environment that Emacs provides. I tested out the following in a *scratch* buffer, created a local key mapping and viola. Just save it in your prefered Emacs init environment and you are done.

(defun back-to-indentation-or-beginning ()
 (interactive)
 (if (= (point)
        (progn
          (back-to-indentation)
          (point)))
     (beginning-of-line)))

(defun killer/python-import-beginning ()
 "Go to the first import statement at the beginning of the buffer.
TODO: Skip any triple-quoted sections at the start of the script/module."
 (interactive)
 (widen) ; turn off narrowing, just in case.
 (goto-char (point-min))
 (if (re-search-forward "^import" nil t)
     (progn
       (goto-char (point))
       (back-to-indentation-or-beginning))
   (message "No python import statement")))

(define-key py-mode-map (kbd "C-; in") 'killer/python-import-beginning)
