Question

What is an ndarray? a two-dimensional array a three-dimensional array an array of any size an array used only in classes

Answer 1

An `ndarray` (short for "n-dimensional array") is a data structure provided by the NumPy library in Python that can represent arrays of any size and dimensionality. Therefore, the correct description is:

**an array of any size.**

`ndarray` can be one-dimensional (like a list), two-dimensional (like a matrix), three-dimensional (like a tensor), or even higher-dimensional. It is a versatile and powerful way to handle numerical data and perform operations on large datasets efficiently.
