It seems your python is not installed with readline support, if
the arrow keys are not working.

You don't need to recompile python for this.
Instead you need to install this.
https://pypi.python.org/pypi/readline

But I am surprised that you need this, as my debian linux unstable
system has this out of the box, more or less always.

I think this is because I have this package installed
https://packages.debian.org/stretch/readline-common
(there are versions for testing and stable as well).

If I were you I would install this first and see if your
arrow problems go away.  If not, get out pip.

I am not sure what you mean by this.
If you, as I, was unhappy as anything about tab in the
interactive console (at the far margin) meaning 'tab complete
every builtin on the planet' rather than 'I'd like another level
of indent please' -- then, 3.5, you are good to go. :)  tabs typed
flush to the margin just indent.  tabs complete if you type them
in the middle of an identifier.

If you mean something else, then, well, explain it a little more, ok?
