What are some common errors when using deepcopy in Python?

What are some common errors when using deepcopy in Python?

Some common errors include not understanding shallow vs deep copies, and mutable objects causing unexpected behavior.

Can you explain the difference between shallow and deep copies?

Sure! 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.

What happens if I use deepcopy on a large object?

Using deepcopy on large objects can lead to significant memory usage and performance issues, as it duplicates everything.

Are there any alternatives to deepcopy?

Yes, alternatives include using shallow copies or manually copying only the necessary parts of an object.
