newdtype
newdtype is a concept primarily associated with the NumPy library in Python. It refers to the creation of custom data types, often referred to as structured data types, that go beyond NumPy's built-in primitive types like integers and floats. These new data types allow users to define arrays where each element is not a single value but a collection of named fields, each with its own specific data type. For example, one could define a newdtype representing a point with 'x' and 'y' coordinates, both as integers, or a person with 'name' (a string) and 'age' (an integer).
The creation of newdtype is achieved using NumPy's `dtype` object. By specifying a list of tuples, where
