Q2.5.1Normalizing a list

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.

Show solution

To normalize a list:

>>> a = [2,4,10,6,8,4]
>>> amin, amax = min(a), max(a)
>>> for i, val in enumerate(a):
...     a[i] = (val-amin) / (amax-amin)
...
>>> a
[0.0, 0.25, 1.0, 0.5, 0.75, 0.25]
