Sure! Here's a simple example: class A: def __init__(self): self.b = B(self) and class B: def __init__(self, a): self.a = a.

What are the best practices to avoid circular references?

To avoid circular references, you can use weak references with the weakref module or design your classes to minimize interdependencies.
