(i) Official explanations

NumPy is the fundamental package for scientific computing with Python. It contains among other things:

• A powerful N-dimensional Array object
• Sophisticated (broadcasting) functions
• Tools for integrating C + + and Fortran code
• Useful linear algebra, Fourier transform, and random number capabilities

Besides its obvious scientific uses, NumPy can also is used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide variety of databases.
