How to sort the outer and inner sublist of a nested list in Python?

Question

First of all, apologies if this too naive (I am a beginner). I have the following type of list of lists, which I would like to first sort by the last member of the inner li

Answer 1

>>> data =  [[1, .45, 0], [2, .49, 2], [3, .98, 0], [4, .82, 1], [5, .77, 1], [6, .98, 2] ]
>>> sorted(data, key=lambda x:(x[2], -x[1]))
[[3, 0.98, 0], [1, 0.45, 0], [4, 0.82, 1], [5, 0.77, 1], [6, 0.98, 2], [2, 0.49, 2]]

You can add extra terms to the lambda as required
