What is the lifetime of an object in Python?
In Python, the lifetime of an object is determined by its reference count. An object exists as long as there are references to it.
How does reference counting work?
Reference counting keeps track of the number of references to an object. When the count drops to zero, the object is deallocated.
What happens if there are circular references?
Circular references can prevent reference counting from deallocating objects. Python uses a garbage collector to handle these cases.
Can you give an example of a circular reference?
Sure! If object A references object B and object B references object A, they create a circular reference.
