Python - Move a text file to a folder automatically

Steps

0. End result. Move only text files created on foo and bar folders to home folder

1. Create demo.py and copy / paste following codes.

   import shutil
   import time
   
   from watchdog.events import PatternMatchingEventHandler
   from watchdog.observers import Observer
   
   class FolderHandler(PatternMatchingEventHandler):
   
       def __init__(self, target_folder, *args, **kwargs):
           super().__init__(*args, **kwargs)
           self.target_folder = target_folder
   
       def on_created(self, event):
           # to prevent PermissionError: [Errno 13] Permission denied:
           time.sleep(1)
           
           shutil.move(event.src_path, self.target_folder) # move source file to target folder
   
   if __name__ == '__main__':
       # source_folder: watching folder, target_folder: move file to folder.
       folders = {
           'foo': {
               'source_folder': './foo',
               'target_folder': './home'
           },
           'bar': {
               'source_folder': './bar',
               'target_folder': './home'
           }
       }
   
       observer = Observer()
   
       for _, folder in folders.items():
           # patterns: txt file only
           event_handler = FolderHandler(target_folder=folder['target_folder'], patterns=['*.txt'],  ignore_directories=True, case_sensitive=False)
           
           observer.schedule(event_handler,  folder['source_folder'],  recursive=True)
   
       observer.start()
   
       try:
           while True:
               time.sleep(1)
   
       except KeyboardInterrupt:
           observer.stop()
   
       observer.join()
   

2. Run demo.py. Ctrl + F5 or Right click >> "Run Python File in Terminal" within VS Code.

3. Create text files in foo and bar folders.

4. Create files in other formats in foo and bar folders.
