Test your knowledge: Python Copying Objects

Review

1. After shallow = copy.copy(source), where source is a list of lists, which relationship normally holds?

   The outer lists are distinct, while their existing inner objects are shared.
2. What happens if you append to an inner list shared by a shallow copy?

   The outer objects differ, but the child list is the same object.
3. Why can copy.deepcopy() copy a recursive list without looping forever?

   The memo helps handle recursive objects and preserves internal sharing/cycles.
4. Which statement about copy.replace(record, title="Final") is correct?

   copy.replace supports dataclasses, named tuples, and classes implementing __replace__; it does not promise a deep copy.
5. A nested list in a copied configuration must be independently mutable. Which operation is the direct fit?

   deepcopy recursively copies nested compound objects where possible; still check whether copying is appropriate for every contained resource.
