^Downloadable code & more! np.empty
Lets start ipython and import numpy as np.
np.empty is a good way to initialize arrays. so lets make an array called initial. np.empty takes in the shape as a tuple.
And lets see what that looks like. As you can see it’s not REALLY empty but just is filled with random data.
Notice the nan or not a number.
so now that it is initialized you can fill it according to whatever algorithm you are use.
So let’s just fill up each column with a number index
and now initial is updated and filled.
So there you have it, that is how you can initialize arrays using numpy’s empty function.
