Emacs C-c C-c for python code

I'm new to using emacs as an IDE to python. I have pymode and Ropemacs active. My understanding is that I should be able to highlight a region then use C-c C-c to send it to an interactive terminal. Are there additional packages that I need to accomplish this?

The error I'm getting for C-c C-c is:

Wrong type argument: integer-or-marker-p, nil

I saw also this link had a statement on that, but that didn't look like my error.

Update answering Zack

To set that variable, I went into emacs scratch and did this:

(setq debug-on-error t)

Then M-x eval-region

(Is that the right way to set that to true?)

Then this is what appeared in my debugger:

Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)

The error shown results from a bug in python-mode.el, which is fixed in trunk. AFAIK the bug only occurs when executing a non-saved buffer, so saving the buffer first makes C-c C-c work.

BTW py-execute-region RET is C-c |, while C-c C-c will always send the whole buffer, regardless of an existing region. If C-c C-c should honor a region, that might be worth a feature request. If interested, please file it here:

https://bugs.launchpad.net/python-mode

Still a personal view: marking a region as such is a costly--e.g. a laborious thing, as it requires some attention defining the borders right, which is spent better at the issue at stake itself. Python-mode will take a lot of this work from you by offering a couple of commands what-to-execute. Maybe have a look into the menu "Python", see section "Execute..." and button "More...". In a similar way a couple of other edits should be made easier.
