Using Spyder / Python to Open .npy File

Question

Sorry. I'm just now learning Python and everything there is to do with data analysis.

How on earth do I open a .npy file with Spyder? Or do I have to use another program? I'm using a Mac, if that is at all relevant.

Answer 1

*.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') 

Answer 2

Given that you asked for Spyder, you need to do two things to import those files:

1. Select the pane called Variable Explorer

2. Press the import button (shown below), select your .npy file and present Ok.

   

Then you can work with that file in your current Python or IPython console.
