Divide elements of a list by a number

Division

You can do:

myList = [1,2,3,4,5,6,7,8,9]
myInt = 10
newList = [float(i) / myInt for i in myList]

Or if you need to keep the reference in the original list

myList[:] = [float(i) / myInt for i in myList]

You can also use the NumPy

import numpy as np
myArray = np.array([1,2,3,4,5,6,7,8,9])
myInt = 10
newArray = myArray/myInt

Normalization

Now if you want to normalize against the unit using the sum:

mySum = sum(myArray)
norm = [float(i)/mySum for i in myArray]

or by using the maximum:

myMax = max(myArray)
norm = [float(i)/myMax for i in myArray]
