My Python library, mathpy, a collection of mathematical and statistical functions with Excel integration, has a new release! Version 0.2.0 introduces a ton of additional mathematical and statistical functions have been added in this release along with a large effort centered on documentation and testing.

Installing the package is easily accomplished through pip:

pip install mathpy

• Binomial Distribution

The next release will center on implementing more of these functions as Excel UDFs and updating the Excel integration and documentation in accordance with the more recent versions of xlwings.

The Python module containing the Excel UDFs can be downloaded from the following link or from the project repository on Github.
Excel UDF Python module

Each release will include an accompanying Excel UDF Python module.

For more information on using the mathpy UDFs, please see the xlwings documentation here.
