That is usually exactly what you want: if a dictionary contains an object, the object should remain available while the dictionary needs it.</p> <p>Some infrastructure has a different requirement. A cache, registry, or metadata table may want to refer to an object without becoming the reason that object stays alive forever. Python&rsquo;s <code>weakref</code> module provides references and containers for that ownership model.</p>
