updated python 2 vs 3 (fixes #48)

it’s 2014.

It's 2014 and the core developers are still back-pedaling on APIs and other things to make the transition easier, because it's still realistically hard.

true in some cases, which is why i only changed the following phrase

This ranges from tricky to extremely hard depending upon the kind of software you are writing

to

This ranges from trivial to hard depending upon the kind of software you are writing

instead of to

This is trivial

:)

[sigmavirus24]

This is still true

i think this paragraph is redundant, as the following one pretty much says the same.

also usually “writing code that works in both Python 2 and Python 3 is not a very complicated process.” it’s actually pretty trivial for most small libraries or programs. just import everything from __future__ and create some wrappers around APIs that use bytes on python 2 and strs on python 3, and you’re set. i think the following paragraph serves to explain that.

We're so close to getting to this point, but I don't feel that we're quite there yet. Honestly, I have been wanting to update this section for quite some time now. But, I feel like this is a little too one-sided, perhaps.

Of course, the guide should be very opinionated, and rightfully so. However, I think we need to do a bit more to paint the picture of the current state of things for the readers.

I am going to merge this, and drastically edit it.

a typo!

The answer is not as obvious as one might thing think

still a bit one-sided in one place, too, although much better than before!

Python 3 introduced major changes to the language, which many developers are unhappy with.

eh, and many are grateful for them and can’t imagine living without them. maybe call them “controversial”?

also, the two phrases “Use Python x if you love Python x” are pretty redundant, don’t you think? if they love a version, we won’t sway them with this guide!

but i’m happy with it now!
