What are some examples of finalizers in Python?

Finalizers in Python are used to define cleanup actions when an object is about to be destroyed. A common example is using the __del__ method.

Can you show me a code example of using del?

Sure! Here's a simple example:

class MyClass:
    def __init__(self, name):
        self.name = name
    
    def __del__(self):
        print(f'{self.name} is being deleted')

obj = MyClass('TestObject')
del obj  # This will trigger the __del__ method

Are there any limitations to using del?

Yes, using __del__ can lead to issues, especially with circular references. It's often better to use context managers.

What are context managers?

Context managers are used to manage resources, ensuring they are properly acquired and released. They are typically implemented using the with statement.
