Python Batch Shuffle, Reorder, and Rename Files in a Folder

I have tens of thousands of images that need to be shuffled, reordered, and renamed. Let’s implement this using Python.

First, batch shuffle the files in the folder.

Second, reorder the files.

Third, batch rename them.

import os, random, time

def rename():
    # Configuration
    # File extension
    filetype = '.png'
    # File name prefix
    filename = ''  
    # Number of digits in the filename, padding zeros in the beginning if less
    zfillNum = 5
    # Configure the folder path here
    path = r"C:\Users\xxxx\Desktop\test"
    i = 0
    filelist = os.listdir(path)   # All files in the folder (including subfolders)

    # Shuffle the order first
    random.shuffle(filelist)
    for files in filelist:   # Iterate through all files
        Olddir = os.path.join(path, files)    # Original file path
        if os.path.isdir(Olddir):       # Skip if it's a folder
            continue   
        filenameRes = str(int(time.time()) + random.randint(1000000, 88888888))
        Newdir = os.path.join(path, filenameRes + filetype)   # New file path
        os.rename(Olddir, Newdir)    # Rename

    filelist = os.listdir(path)   # All files in the folder (including subfolders)
    for files in filelist:   # Iterate through all files
        i = i + 1
        Olddir = os.path.join(path, files)    # Original file path
        if os.path.isdir(Olddir):       # Skip if it's a folder
            continue   
        filenameNum = str(i).zfill(zfillNum)
        filenameRes = filename + filenameNum
        Newdir = os.path.join(path, filenameRes + filetype)   # New file path
        os.rename(Olddir, Newdir)    # Rename
    return True

if __name__ == '__main__':
    rename()
