NumPy Financial
The numpy-financial package contains a collection of elementary financial
functions.
The financial functions in NumPy are deprecated and eventually will be removed from NumPy; see NEP-32 for more information. This package is the replacement for the original NumPy financial functions.
The source code for this package is available at https://github.com/numpy/numpy-financial.
The importable name of the package is numpy_financial. The recommended
alias is npf. For example,
>>> import numpy_financial as npf
>>> npf.irr([-250000, 100000, 150000, 200000, 250000, 300000])
