What is a weak reference in Python?

Q: What is a weak reference in Python?

A **weak reference** (`weakref`) points to an object **without** increasing its reference count — so it does **not keep the object alive**. When the last *strong* reference disappears, the object is collected even though weak references still 'point' at it; those weakrefs then return **`None`** (or fire a callback): strong ref weak ref <text class='d-text' x='375' y='82' tex
