One issue I ran into is functions that modify values passed by reference. Python was designed to avoid this sort of thing, at least for the fundamental types, and so you have to do some annoying array('i', [0]) Yo, dude. You may use integerVariable = ROOT.Long() Actually works too.

Yo, dude. You may use

integerVariable = ROOT.Long()

Actually works too.
