Python : How do i rename all files in folder so that they get UUID name (renaming all files in folder ) ?

RenameFilesInFolderToGetUUIDNames.py

import uuid
import os

def get_extension(name):
    return name.split('.')[-1]

def get_list_of_files_only_in_folder(folder_path):
    return [f for f in os.listdir(folder_path) if os.path.isfile(os.path.join(folder_path, f))] #

def rename_all_files_inside_folder(folder_path):
    onlyfiles = get_list_of_files_only_in_folder(folder_path)
    path_fileName_newFileName = [(mypath, i, str(uuid.uuid4()) +"." + get_extension(i)) for i in onlyfiles]
    
    for path, old_name, new_name in path_fileName_newFileName:
        os.rename(path + "\\"+ old_name, path + "\\"+ new_name)

rename_all_files_inside_folder("C:\\Users\\cosmos\\Desktop\\pix2pix_deep_learning")
#print(path_fileName)
