Deleting folders in python recursively

Try shutil.rmtree:

import shutil
shutil.rmtree('/path/to/your/dir/')

Here's my pure pathlib recursive directory unlinker:

from pathlib import Path

def rmdir(directory):
    directory = Path(directory)
    for item in directory.iterdir():
        if item.is_dir():
            rmdir(item)
        else:
            item.unlink()
    directory.rmdir()

rmdir(Path("dir/"))

The default behavior of os.walk() is to walk from root to leaf. Set topdown=False in os.walk() to walk from leaf to root.
