org-babel python eval discrepancy

org-babel python eval discrepancy

Hi,

I have the following code block in my org mode based literate programming
notes:

#+BEGIN_SRC python
print('1+2 > 4 is ', 1+2 > 4)
print("What is 3 + 2?", 3 + 2)
#+END_SRC

When I tangle it and run the script, it gives me expected output as follows:

> python notes.py
1+2 > 4 is  False
What is 3 + 2? 5

However, in buffer evaluation (using =C-c C-c= with cursor on src block)
gives me the following output, which seems unexpected:

#+BEGIN_SRC python
print('1+2 > 4 is ', 1+2 > 4)
print("What is 3 + 2?", 3 + 2)
#+END_SRC

#+RESULTS:
: ('1+2 > 4 is ', False)
: ('What is 3 + 2?', 5)

Any hints what may be going wrong?

Shell is using python3 and org-mode python2?

Hey Dov,

Bull's eye! Never realized that could hurt.

It so happened that I set the correct python version in my shell before
starting emacs. However, my bashrc file was hardwired to a different
version, which org used every time for evaluating the src blocks.

Thanks for the help!

Lookup "Org babel results" in Google and you should find the right
section of the manual.  You need to set the :results keyword.
