NumPy: Save two given arrays into a single file in compressed format and load it

NumPy: Basic Exercise-36 with Solution

Write a NumPy program to save two given arrays into a single file in compressed format (.npz format) and load it.

Sample Solution :

Python Code :

import numpy as np
import os
x = np.arange(10)
y = np.arange(11, 20)
print("Original arrays:")
print(x)
print(y)
np.savez('temp_arra.npz', x=x, y=y)
print("Load arrays from the 'temp_arra.npz' file:")
with np.load('temp_arra.npz') as data:
    x2 = data['x']
    y2 = data['y']
    print(x2)
    print(y2)

Sample Output:

Original arrays:
[0 1 2 3 4 5 6 7 8 9]
[11 12 13 14 15 16 17 18 19]
Load arrays from the 'temp_arra.npz' file:
[0 1 2 3 4 5 6 7 8 9]
[11 12 13 14 15 16 17 18 19]
