I have an unknown .npz file and would like to see whats inside. I am very new to Python.
>>> import numpy
>>> b = numpy.load('data.npz')
>>> print(b.files)
['arr_1', 'arr_0', 'arr_3', 'arr_2']
How do I see what these arr_i contain (i.e. dimension, values, etc.)?

np.savez_compressed('filename.npz', array1=array1, array2=array2)
b = np.load('filename.npz')
And do b['array_1'], b['array_2'] and so on to retrieve data from each array.
Python provides "npzviewer" to open .npz files
pip install npzviewer
npzviewer [-h] [-v] [npzfile]
