running Python code with interaction

[Stefan Vollmar]

Hello,

I have been using the following code for developing simple Python programs with 
Emacs (mostly copied from some very helpful postings on this list - thanks):

(defun py-run-arg (arg)
  "run code in current buffer with Python interpreter"
  (interactive "sarg: \n")
  (save-buffer)
  (condition-case nil (delete-process "*compilation*") (error nil))
  (condition-case nil (kill-buffer "*compilation*") (error nil))
  (compile
   (format "python \"%s\" %s"
                   (buffer-file-name) arg)))

(global-set-key [(f1)] 'py-run-arg)

In case of errors, offending lines will be displayed in red colour and can be 
used as links to the offending code (courtesy of "compile") - neat!

This version also takes an argument which is passed to the Python interpreter. 
However, while this approach covers a lot of cases well, I occasionally wish to 
interactively enter data while a program is running and waiting for user input. 
Sometimes it is also desirable to have a special input mode for passwords and 
this is what you get when you run something like this code (Python) in a shell:
PASSWD = getpass.getpass()

Yes, I can switch to an Emacs shell and execute my Python code in commandline 
fashion (without leaving Emacs, which is the point). However, I want to start 
the code as conveniently as the above example (press <f1> to run the code of 
the current buffer) and, if possible, have automatic links to error lines (as 
compile mode provides). Is this possible?

Many thanks in advance.
Warm regards,
 Stefan
