Which method in Python is used as a destructor?  __delete__  __del__  __destroy__  __end__

In Python, the method used as a destructor is __del__.

Explanation:

The __del__ method is called when an object is about to be destroyed, meaning when the reference count of the object reaches zero. This provides a way to perform any necessary cleanup, such as releasing resources or saving state, before the object is removed from memory.

Here’s how it works:

1. Automatic Invocation: Unlike other methods, __del__ is invoked automatically by the Python garbage collector.
2. Defined as a Class Method: You define it within a class, and when an instance of the class is deleted (or goes out of scope), the __del__ method is executed.
3. Caution in Usage: It's important to be cautious when using __del__, since circular references can lead to objects not being destroyed as expected.

In summary, amongst the options given, __del__ is the correct answer for the destructor method in Python.
