Transfer last images in file to another

Question

I'm trying to find python code to transfer the last 10 or so images to another file.

import os
import shutil
import fnmatch

source = 'the folder name'
destination = 'folder name'

def get_latest_image(source, y=('jpg')):
    valid_files = [os.path.join(source, destination) for destination in os.listdir(source)]
    valid_files = [f for f in valid_files if '.' in f and \
    f.rsplit('.',1)[-1] in y and os.path.isfile(f)]
    for f in files:
        if fnmatch.fnmatch(f,y)==True:
            shutil.move(source + f, y + f)

... This is the code I tried using if you could possibly help me figuring out the code it would really help
