The financial functions of numpy have been deprecated and will be removed from future versions. Once we’ve learned how to import large sets of information from external text files, we’ll finally be ready to explore one of NumPy’s strengths – statistics. NumPy is a Python library that adds an array data type to the language, along with providing operators appropriate to working on arrays and matrices. Since the package is extremely computationally durable, we often rely on its functions and methods to calculate the statistics of a sample dataset. Until recently, NumPy in Python had simple, but useful financial functions. 2.
