Using plt.imshow() to display multiple images

How do I use the matlib function plt.imshow(image) to display multiple images?

For example my code is as follows:

for file in images:
    process(file)

def process(filename):
    image = mpimg.imread(filename)
    <something gets done here>
    plt.imshow(image)

My results show that only the last processed image is shown effectively overwriting the other images

You can set up a framework to show multiple images using the following:

import matplotlib.pyplot as plt
import matplotlib.image as mpimg

def process(filename: str=None) -> None:
    """
    View multiple images stored in files, stacking vertically

    Arguments:
        filename: str - path to filename containing image
    """
    image = mpimg.imread(filename)
    # <something gets done here>
    plt.figure()
    plt.imshow(image)

for file in images:
    process(file)

This will stack the images vertically

To display the multiple images use subplot()

plt.figure()

#subplot(r,c) provide the no. of rows and columns
f, axarr = plt.subplots(4,1) 

# use the created array to output your multiple images. In this case I have stacked 4 images vertically
axarr[0].imshow(v_slice[0])
axarr[1].imshow(v_slice[1])
axarr[2].imshow(v_slice[2])
axarr[3].imshow(v_slice[3])
