Tuples Are Unnecessary. In Visual Basic tuples and the ValueTuple types, tuple fields are read-write; the tuples are mutable. It will be helpful in use cases where we want to leverage the power of NumPy operations on existing data structures. Moreover, to create an array, you'll need to specify a value type. So, we can easily assign or insert value using an index as well. ... You can look into Numpy Arrays vs Lists to know more. Arrays vs sets vs tuples. With arrays, all the items in the collection type must be of the same data type. They both have a fixed size. It offers more types and stronger type checking than JavaScript.

Mutable, 2. List is like array, it can be used to store homogeneous as well as heterogeneous data type (It can store same data type as well as different data type). Generally speaking, if you're not working with expression trees , and you're comfortable with tuple syntax then choose ValueTuple as they provide a value type with the flexibility to name properties. Once you define the tuple you can then use it to declare variables. How can I subtract tuple of tuples from a tuple in Python?
