Do i use python 3.3 or 2.7? I see there is a difference using the print syntax in these versions. I believe the course uses 2.7 but not sure. Can anyone please confirm?

the course uses python 2.x, and most of the tutorials and books assume it. if you have 3.x installed, there really is no problem, although there are mostly minor differences - no raw_input in 3.x, input is a completely different function in 3.x ( but not a problem from a programming viewpoint), x/y behaves differently (x//y behaves like x/y) .
yes, that doesn`t make much difference....but you will find tutorials and material for python 2.x more easily and moreover the course uses 2.x . i my view 2.x would be better
Python 3 will only confuse you. Go for 2 first, master it, then pick up new 3 syntaxes.

I would use whatever the course recommends (2.5 I believe). If you actually go on to use Python professionally then you can keep up to date by reading release notes.
Try to learn version 3 but use 2.7
i would recommend you to use 2.5.4
2.5.4 is outdated. Do not use. Use 2.7 instead, it is the latest version in the 2.x branch.
Thank you ! for the help
