Move all files from subfolders in a parent directory up to the parent directory. It essentially flattens a folder structure, dumping all files into the parent folder.

files2parent.py

 import os
 import shutil
 
 target = input("What is the starting directory?")
 def files2parent(target):
     for root, dirs, files in os.walk(target): 
        for file in files:
         try:
           path_file = os.path.join(root,file)
           shutil.move(path_file,target) 
         except: pass
