Org-mode version 8.0-pre (release_8.0-pre-203-g9= 93e3e @ /home/evan/Documents/org/elisp/org-mode/lisp/)
GNU Emacs 24.3.1 = (x86_64-unknown-linux-gnu, GTK+ Version 2.24.10) of 2013-03-21 on evan-Dell= -System-Inspiron-N7110 [2 times]

I installed the patched version.=A0 It does hold session definiti= on:

#+name: second-deriv-function
#+begin_src python :session=A0 = :results output :exports code
=A0 def diff2(f, x, h=3D1E-6):
=A0=A0= =A0=A0=A0=A0=A0 """Function that takes the second derivative= """
=A0=A0=A0=A0=A0=A0=A0 r=3D(f(x-h)-2*f(x)+f(x+h))/float(h*h)
=A0=A0=A0=A0= =A0=A0=A0 return r

#+end_src
#+RESULTS: second-deriv-function
=
Now let's write a target function, say $g(t)=3Dt^{-6}$:
#+name: = target-funtion
#+begin_src python :session :results output :exports code=
=A0 def g(t):
=A0=A0=A0=A0=A0 """well behaved target func= tion"""
=A0=A0=A0=A0=A0 return t**(-6)

#+end_src
#+RESULTS: target-funtion

Now let's define the second deri= vative and evaluate it at $t=3D1.2$

#+name: evaluating-the-target
#+begin_src python :session=A0 :result= s output :exports both
=A0 t=3D1.2
=A0 d2g =3D diff2(g,t)
=A0 prin= t "g''(%f)=3D%f" % (t, d2g)
#+end_src

#+RESULTS= : evaluating-the-target
:
: >>> g''(1.200000)=3D9.767798

But it d= oes not appear to support named session:

Works with a named session.=
#+begin_src python :session foo
=A0 x =3D 9
=A0 x
#+end_src
#+RESULTS:
: None

#+begin_src python :session foo
=A0 x
#+e= nd_src

#+RESULTS:

Thanks,

Evan

Sorry, I'm not going to do this work for you. =A0If you want to t= ake a
shot at re-working ob-python, then you're welcome to. =A0However, I wou= ld
recommend first reading through some of the history which lead to its
current state, and fully understanding what that current state is (which at a minimum means reading and digesting the relevant documentation).

You will. :)

Best of luck,
