How do I correctly clean up a Python object?

Question

class Package:
    def __init__(self):
        self.files = []

    # ...

    def __del__(self):
        for file in self.files:
            os.unlink(file)
         


        

Answer 1

A better alternative is to use weakref.finalize. See the examples at Finalizer Objects and Comparing finalizers with __del__() methods.
