Hi list, I was banging my head about a pythonic way of doing the following,
Given a nested list, how do I sort the uppermost list based on one key and when a special condition occurs a sort on another key should be performed? For example, [[1,2], [2, 2], [3, 2], [4, 0]] would be sorted, in my example as, [[4, 0], [3, 2], [2, 2], [1, 2]]. That is, sort on the second value and in case they are equal, reverse sort on the first value. I tried doing this using sorted and using a custom cmp function but not sure about how to define the cmp function. -- Sarma Tangirala, Class of 2012, Department of Information Science and Technology, College of Engineering Guindy - Anna University
