When should I use weak references in Python?
Weak references are useful when you want to reference an object without preventing it from being garbage collected.
Can you give me an example of when weak references would be beneficial?
Sure! They are often used in caching scenarios where you want to allow cached objects to be collected when memory is needed.
Are there any downsides to using weak references?
Yes, the main downside is that weak references can lead to unexpected behavior if the referenced object is collected while you're still trying to use it.
