I am running and interactive ipython shell in an emacs buffer using
ipython.el. I wonder if there is a way to clear the screen? Since it is not running on a terminal, the
import os; os.system('CLS') trick will not work. Thanks.

It looks like ipython is based on comint, which means the following code should work for you (called with
M-x my-clear or your favourite key binding):
(defun my-clear () (interactive) (let ((comint-buffer-maximum-size 0)) (comint-truncate-buffer)))
I posted some other options in response to esta pregunta.
C-c M-o runs the command comint-clear-buffer (found in inferior-python-mode-map), which is an interactive compiled Lisp function.
It is bound to C-c M-o.
Clear the comint buffer.
This clears the screen y the current session variables (using
(defun my-reset-ipython () "Clear Emacs *Python* buffer and resets iPython variables. Prints date and time of reset to iPython console and to *Messages* buffer.
