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

Some common errors include shallow copying mutable objects, forgetting to import the module, and using copy on non-copyable objects.

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. This means changes to mutable objects in the copied structure can affect the original.

What happens if I try to copy a non-copyable object?

If you try to copy a non-copyable object, Python will raise a TypeError, indicating that the object cannot be copied.

How can I avoid these errors when using the copy module?

To avoid errors, always check if the object is copyable, use deep copies for nested structures, and ensure you import the copy module correctly.
