Normalizing a list

Question Q2.5.1

Write a python program to normalize a list of numbers, a, such that its values lie between 0 and 1. Thus, for example, the list a = [2,4,10,6,8,4] becomes [0.0, 0.25, 1.0, 0.5, 0.75, 0.25].

Hint: Use the built-ins min and max which return the minimum and maximum values in a sequence respectively; for example: min(a) returns 2 in the above list.
