Sorting a tuple that contains tuples

I am having some trouble with sorting a tuple which contain number and string.
in the beginning, I have a tuple like this:

a=(("a",2),("b",2),("a",1))

then how can I sort it into: (by number first then alphabetical)

a=(("a",1),("a",2),("b",2))

Thank a lot for your help!

Answer 1

>>> a=(("a",2),("b",2),("a",1))
>>> from operator import itemgetter
>>> sorted(a, key=itemgetter(1, 0))
[('a', 1), ('a', 2), ('b', 2)]
