What are the limitations of namedtuple?

What are the limitations of namedtuple in Python?

Namedtuples are great for creating lightweight, immutable objects, but they have some limitations. For instance, they don't support default values for fields, and their immutability can be a drawback if you need to modify data frequently.

Can you give me an example of when namedtuple might not be suitable?

Sure! If you need to create a data structure that requires mutable fields, like a configuration object that changes over time, a namedtuple would not be suitable. Instead, you might want to use a regular class or a dictionary.

Are there performance issues with namedtuple?

Namedtuples are generally efficient, but they can be slower than regular tuples due to the additional overhead of field names. If performance is critical and you don't need named fields, a regular tuple might be a better choice.

What about type checking with namedtuple?

Namedtuples don't enforce type checking, so you can accidentally assign incorrect types to fields. If type safety is important, consider using data classes or type annotations with regular classes.
