What are the benefits of using the weakref module in Python?

The weakref module allows you to create weak references to objects, which can help manage memory more efficiently.

Can you explain how weak references differ from strong references?

Sure! Strong references keep an object in memory as long as the reference exists, while weak references do not prevent the object from being garbage collected.

When should I consider using weak references?

You should consider using weak references when you want to avoid circular references or when caching objects without preventing their garbage collection.

Are there any performance implications of using weak references?

Yes, using weak references can improve performance by reducing memory usage, but they may introduce slight overhead due to additional checks for object existence.
