What is the difference between copy and deepcopy in Python?

What is the difference between copy and deepcopy in Python?

In Python, a 'copy' creates a shallow copy of an object, while 'deepcopy' creates a new object and recursively adds copies of nested objects.

Can you give me an example of when to use deepcopy?

Sure! Use deepcopy when you want to modify a nested object without affecting the original object.

What happens if I use copy on a list of lists?

Using copy on a list of lists will create a new list, but the inner lists will still reference the original inner lists.

Is deepcopy slower than copy?

Yes, deepcopy is generally slower than copy because it has to recursively copy all nested objects.
