What are some common errors when using the copy module in Python?

Some common errors include shallow copying mutable objects, which can lead to unexpected behavior.

Can you explain what shallow copying means?

Shallow copying creates a new object but inserts references into it to the objects found in the original.

What about deep copying? How is it different?

Deep copying creates a new object and recursively adds copies of nested objects, preventing reference issues.

When should I use deep copy instead of shallow copy?

Use deep copy when you need to duplicate complex objects with nested structures to avoid unintended modifications.
