When should I use deepcopy in Python?

When should I use deepcopy in Python?

You should use deepcopy when you want to create a new object that is a copy of an existing object, including all nested objects.

Can you give me an example of when deepcopy is necessary?

Sure! If you have a list of lists and you modify a nested list, using deepcopy ensures that the original list remains unchanged.

What happens if I use a regular copy instead?

Using a regular copy will create a shallow copy, meaning changes to nested objects will affect the original.

Are there performance considerations with deepcopy?

Yes, deepcopy can be slower and use more memory than a shallow copy, especially for large or complex objects.
