[O] [babel] python sessions

[Andrea Crotti]

I wanted to use sessions in python to do some nice literate programming
and splitting functions, but it doesn't work as expected.

Here below a very simple example in python and ruby, where in ruby
everything seems to work well while in python it doesn't...
And by the way, what is that org_babel_python_eoe? I can't find it
documented anywhere in the manual...

I've read some time ago that python support for babel was a bit tricky,
are there workarounds to make it work anyway?

Or could you explain briefly what the problem is so that I can try to
contribute as soon as I finish this thing?

Thanks a lot,
Andrea
