What is the difference between NumPy and SciPy?

Hi, What is the difference between NumPy and SciPy

NumPy is the fundamental package for scientific computing, providing n-dimensional arrays and some common numeric routines. SciPy (library) adds some more. The slightly confusing part is that ScipPy is also a larger project that groups together, among others, NumPy, SciPy library, matplotlib and Pandas.
