It will take you an hour at most to read up on all the significant changes in Python 3. Its not like learning Scala or Perl at all. It just cuts some things that have been depreciated for years, makes everything more consistently iterable, adds some nice new comprehensions and literals, modifies certain bits of metaprogramming, and a few other smaller changes. The hardest thing for me was remembering that print is a function in 3, and needs parens.

@a1a I apologize, I was a jerk yesterday. I definitely dropped my forum manners. Not ok!

Just so you do know what the story is with python3: It's mostly a move to proper unicode support (which couldn't be done without breaking backwards compat) but it's a relatively minor change for most code. You'll definitely run into some library support issues, but they should be few and getting fewer. It shouldn't be terrible, and I'd encourage you to do it just for the sake of Guido and the python community, because this transition has been a bit of a burden for them.

> I have no use of python 3

You admit you haven't done any research, so you clearly don't have any basis for making that statement.
