I would like to create a game on Pygame and copy the linescript in opensesame for collect data. I want to know what version of python I must to use (3 or 2) and what version of pygame too.
You can use either Python 2 or 3, and the version of PyGame would then be the version that's bundled with OpenSesame, which you can check by inspecting the pygame.__version__ property in the debug window.
If you're trying to run PyGame scripts in OpenSesame, it's important to be aware that OpenSesame has already created a window surface for you, so you should patch the script such that it doesn't create another one. (The details of course depend on the script.)
