Numpy - Import Numpy and Create an array

The NumPy library contains multidimensional array and matrix data structures.
It provides ndarray, a homogeneous n-dimensional array object, with methods to efficiently operate on it.
NumPy can be used to perform a wide variety of mathematical operations on arrays.
It adds powerful data structures to Python that guarantee efficient calculations with arrays and matrices and it supplies an enormous library of high-level mathematical functions that operate on these arrays and matrices.
