strange behavior with org-babel python

strange behavior with org-babel python

[Doyley, Marvin M.]

Hi there,

If run the follow codes I get the following, could someone explain to me what is going wrong

(1) The desired results
#+BEGIN_SRC python :results output :exports both :session
x=5
def foo(x):
	if x>0:
		return x+1
	else:
		return x-1

print(foo(x))
#+END_SRC

#+RESULTS:
: 6

(2) No results
#+BEGIN_SRC python :results output raw :exports both 

x=5
if x>0:
	x= x+1
else:
	x= x-1
print(x)
#+END_SRC

#+RESULTS:


(3) Not sure, why I get this error
#+BEGIN_SRC python :results output raw :exports both :session

x=5
if x>0:
	x= x+1
else:
	x= x-1
print(x)
#+END_SRC

#+RESULTS:

>>> >>> >>> >>> ... ...   File "<ipython-input-5-f6e13edbe7ef>", line 3
    else:
         ^
IndentationError: unindent does not match any outer indentation level

If you want to paste code into IPython, try the %paste and %cpaste magic functions.

Thanks,
M

PS in .emacs, I have (setq org-babel-python-command "ipython --no-banner --classic --no-confirm-exit")

To reliably paste code blocks into IPython, you will have to use
%cpaste magic command.  See any of these links[1][2][3] for code you
can reuse.

Hope that helps,

Thanks, this works when I use :session,
but I don’t get any results when I am not running a session. 
Doy you know why this is the case?

Cheers,
M

I'm not sure what is going on here, and have not been able to
reproduce your problem.  What version of Emacs and Org-mode are you
using?
