[Python-Dev] str with base

[Jason Orendorff]

It seems dumb to support *parsing* integers in weird bases, but not
*formatting* them in weird bases.  Not a big deal, but if you're going
to give me a toy, at least give me the whole toy!

The %b idea is a little disappointing in two ways.  Even with %b,
Python is still dumb by the above criterion.  And, I suspect users
that don't know about %b are unlikely to find it when they want it.  I
know I've never looked for it there.

I think a method 5664400.to_base(13) sounds nice.
