Numpy Trick 01

I usually forget how much Numpy makes life easy :

Say, you have a 101 element array, e.g.:

import numpy as np

a = np.linspace(0,100,101)

and you want to take every 4th item in that array, that’s as easy as :

print a[::4]

will output:

array([0., 4., ... , 96., 100.])

I love Numpy !
