How to do it...

Here is the code block that reads a JPEG file as a pixel-valued list and displays it as an image on the screen:

1. Read the image louvre.jpg into a three-dimensional array (color images have three channels, whereas black and white images have one channel only):

image = plt.imread('louvre.jpg')

2. Print the dimensions of the image:

print("Dimensions of the image: ", image.shape)

3. Plot the image:

plt.imshow(image)

4. Display the image on the screen:

plt.show()
