Shallow copy creates a new object but does not duplicate nested objects, while deep copy creates a new object with all nested objects duplicated.

• Shallow copy only copies the references of nested objects, not the objects themselves.

• Deep copy creates new copies of all nested objects, ensuring complete independence.

• In Python, shallow copy can be achieved using the copy() method, while deep copy can be achieved using the deepcopy() method from the copy module.

Debt to equity ratio is calculated by dividing total debt by total equity.
