What should I learn before attempting Python3?

Answer 1

I guess you could start by learning (if you haven't done so) some basic algorithmics: iteration, flow control, arrays, loops, subroutines-modularization, and program design (in a piece of paper, I should say). Then you'll be able to apply these concepts to Python or to any other programming language.
