Is there a way I can get a numpy array to print out with index numbers like this? Thanks!

You could use numpy.ndenumerate.

please, don't post images of code, error, output, etc. Copy/paste in respective BBcode tags

What BBcode tags should be used for displaying a screenshot (file)?

That gave me something like <numpy.ndenumerate object at 0x0000014BE3A7F9D0> . How do I look at it?

what exactly of NOT POST IMAGE (that is also screeshot) is unclear? copy/paste your code, errors, output, etc.

It's an iterable like what enumerate is.
If you have learned the basics, you should know this simple things.

Please learn Python before you dive into numpy.

import numpy as np


data = np.random.random((10,3,2))

for index, value in np.ndenumerate(data):
    print(index, value)

So if you know Python, the example in the documentation of the function, looks similar to enumerate:

data = ["A", "B", "C"]
for index, value in enumerate(data):
    print(index, value)

And if you want to iterate only over the first dimension:

import numpy as np


data = np.random.random((10,3,2))
for index, value in enumerate(data):
    print(index, value)

This will give you 10 numpy.ndarrays with a shape of (3,2).

Thanks DeaD_EyE!
