How do you open .NPY files?

How do I open .NPY files in python so that I can read them? I've been trying to run some code I've found but it outputs in .NPY files so I can't tell if its working.

Late reply but I think NPYViewer is a tool that can help you, as it allows you to quickly visualize the contents of .npy files without having to write code. It also has options to visualize 2D .npy arrays as grayscale images as well as 3D point clouds.

*.npy files are binary files to store numpy arrays. They are created with

import numpy as np

data = np.random.normal(0, 1, 100)
np.save('data.npy', data)

And read in like

import numpy as np
data = np.load('data.npy')
