Here's what I'd recommend :)

$ sudo apt-get build-dep python3
$ sudo apt-get install mercurial
$ hg clone https://hg.python.org/cpython
$ cd cpython
$ ./configure
$ make
$ sudo make install

That should get you Python 3.6 with a whole lot of new features above
3.2. (And yes, 3.6 and 3.2 can happily coexist too.) After that,
you'll want to use pip exclusively for installing Python modules (you
can use apt-get to grab packages for your 3.2 install, but it won't do
anything for your 3.6), but other than that, you should have a
perfectly working system that runs the very latest in Pythons.
