Test if two lists of lists are equal

Question

Say I have two lists of lists in Python,

l1 = [['a',1], ['b',2], ['c',3]]
l2 = [['b',2], ['c',3], ['a',1]]

What is the most elegant way to test they are equal in the sense that the elements of l1 are simply some permutation of the elements in l2?

Note to do this for ordinary lists see here, however this uses set which does not work for lists of lists.

Answer 1

l1 = [['a',1], ['b',2], ['c',3]]
l2 = [['b',2], ['c',3], ['a',1]]
print sorted(l1) == sorted(l2)

Result:

True
