I am using a snapshot build of Emacs:
emacs-trunk-r112044-20130314-w32-i386.zip, which says it is GNU Emacs
24.3.50.1 (i386-mingw-nt6.1.7601) of 2013-03-14 on VBOX
on Windows 7/64.

My python-mode comes from the python.el shipped with the above emacs, which
says it is Version: 0.24.2.

Org-mode is from git trunk:
 commit 3842b073c332256ebfeecb0b01f859bb720cb68f
