Python: Moving files to folder based on filenames

问题

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, and as of now I've been successful at moving each image filename to its own folder but I've yet to figure out how to move all images with the same filename into one folder and the other to another folder. 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 the image files to a new folder by creating new folders based on it's filename. I got the part on making folders but I'm quite confused when it created separate image folders for all the images.

import os, shutil, glob

#Source file 
sourcefile = 'Desktop/00/'

# for loop then I split the names of the image then making new folder 
for file_path in glob.glob(os.path.join(sourcefile, '*.jpg*')):
    new_dir = file_path.rsplit('.', 1)[0]    
    # If folder does not exist try making new one
    try:
        os.mkdir(os.path.join(sourcefile, new_dir))
    # except error then pass
    except WindowsError:
        pass
    # Move the images from file to new folder based on image name
    shutil.move(file_path, os.path.join(new_dir, os.path.basename(file_path)))

This is what I got after I ran my script.

However, What I'm trying to do is shown in this image below:

You can just try to use os.path.exists() to check if the folder exists, if it exists copy the jpg into it. By the way it's better if you use copy, because when you use move you are basically mixing everything up if you do something wrong.

import os, shutil

os.chdir("<abs path to desktop>")

for f in os.listdir("folder"):
    folderName = f[-6:-4]

    if not os.path.exists(folderName):
        os.mkdir(folderName)
        shutil.copy(os.path.join('folder', f), folderName)
    else:
        shutil.copy(os.path.join('folder', f), folderName)
