What are strong references in Python?

What are strong references in Python?

In Python, a strong reference is the default type of reference. It means that as long as a reference to an object exists, that object cannot be garbage collected.

Can you give me an example of a strong reference?

Sure! If you create a list and assign it to a variable, that variable holds a strong reference to the list. For example: my_list = [1, 2, 3].

What happens if I delete the reference?

If you delete the reference using del my_list, the list can be garbage collected if there are no other references to it.

Are there any situations where strong references can be problematic?

Yes, strong references can lead to memory leaks if objects reference each other, preventing them from being garbage collected.
