Python 3.5: Moving files to folder based on filenames

Question

I have a folder with 10 images that I wish to move into a new folder based on it's current filenames. I've successfully been able to move every images in the folder into a new folder but I've yet to figure out how to move the files based on it's filename, For example below I want to move the images accordingly.

• 1600_01.jpg ---> folder 1
• 1700_01.jpg ---> folder 1
• 1800_02.jpg ---> folder 2
• 1900_02.jpg ---> folder 2
• 2000_03.jpg ---> folder 3
• 2100_03.jpg ---> folder 3

This is my code thus far for moving entire files in a folder to a destination that I want.

# Moving Files from one place to another
import shutil
import os 

sourcefile = 'Desktop/00/'
destination = 'Desktop/00/d'

# Loading the files from source
files = os.listdir(path=sourcefile)

# Reading the files in folder
for f in files:
    shutil.move(sourcefile+f, destination)

Answer 1

At this point all you need is to modify destination based on the last digit:

for f in files:
    folder_number = f.split('.')[0][-1]
    shutil.move(sourcefile+f, destination + '/' + folder_number + '/' + f)
