Python’s Hidden Feature: The WeakRef Module — Managing Objects Without Owning Them! 🚀
Have you ever needed to reference an object in Python without preventing it from being garbage collected? Normally, when you create a reference to an object, Python increases its reference count, keeping it alive. But what if you want a reference that doesn’t interfere with garbage collection?
Enter weakref, one of Python’s hidden gems. 💎
Why Should You Care About weakref?
Python uses automatic garbage collection to free memory when objects are no longer needed. However, circular references and large caches can cause memory leaks if objects stick around longer than required.
With weakref, you can:
✅ Create references that don’t prevent garbage collection
✅ Avoid memory leaks by allowing unused objects to be freed
✅ Implement object caching without bloating memory
Sounds powerful, right? Let’s dive into it!
Understanding Weak References
A weak reference lets you reference an object without increasing its reference count. This means that if there are no strong references to an object, it will still be garbage collected.
