How does a Python custom comparator work?

Question

I have the following Python dict:

[(2, [3, 4, 5]), (3, [1, 0, 0, 0, 1]), (4, [-1]), (10, [1, 2, 3])]

Now I want to sort them on the basis o

Answer 1

Basically, for the simple list such as [2, 4, 6, 3, 1] and the complex list you provided, the sorting algorithms are the same.

The only differences are the complexity of elements in the list and the comparing scheme that how to compare any tow elements (e.g. myComparator you provided).

There is a good description for Python Sorting: https://wiki.python.org/moin/HowTo/Sorting
