How do I copy objects in Python?

In Python, you can copy objects using the copy module. Would you like to know about shallow and deep copies?

Yes, what's the difference between shallow and deep copies?

A shallow copy creates a new object but inserts references into it to the objects found in the original. A deep copy creates a new object and recursively adds copies of nested objects found in the original.

Can you show me an example of both?

Sure! Here's a simple example:

import copy

original = [1, 2, [3, 4]]
shallow_copied = copy.copy(original)
deep_copied = copy.deepcopy(original)

original[2][0] = 'changed'

print(shallow_copied)  # Output: [1, 2, ['changed', 4]]
print(deep_copied)     # Output: [1, 2, [3, 4]]
