This string is used by Babel to indicate when to stop waiting for output
form the interactive python process and return control to the user.

This is true, in addition to being a language which is dependent upon
whitespace characters, python has been tricky due to the many
independent inferior python modes (python.el, python-mode.el, etc...)
and to the fact that I personally and not very familiar with the

I've just pushed up a patch which should improve upon the python session
behavior.  After this patch your example returns the following

--8<---------------cut here---------------start------------->8---
#+begin_src python :session :results silent
  def var(x):
      return float(x ** 2)

#+begin_src python :session :result value
  def var2(x):
      return x ** 2 * var(x)

Please let me know if you notice any other problematic behavior.
