I don't know if it's best, but legend can take a list of objects
and labels, so you can just grab all of the objects from the twin,
and put them all in one legend:
def onelegend_twinaxes(axis,twin):
#make a joint axis legend
lines = twin.get_lines()
lines.extend(axis.get_lines())
labels = [l.get_label() for l in lines]
return axis.legend(lines, labels)
Here's a picture of what that looks like (thought I did some
other prettifications).

I wrote this in a solution set for a class I'm TAing this
semester, so you can look at the whole thing here, if you'd like.
the file is part of the solutions for Lab #1, it's called lab1.py
(but actually links to lab1.txt):
