AssessPy package

AssessPy is a software package for Python developed by the Cook County Assessor’s (CCAO) Data Department. The codebase for the CCAO’s CAMA system uses a wide range of functions regularly, and packaging these functions streamlines and standardizes their use. The CCAO is publishing this package to make it available to assessors, reporters, and citizens everywhere.

For assessors, we believe that this package will reduce the complexity of calculating ratio statistics and detecting sales chasing. We also believe that reporters, taxpayers, and members of academia will find this package helpful in monitoring the performance of local assessors and conducting research.

For detailed documentation on included functions and data, visit the full reference list.

For examples of specific tasks you can complete with assesspy functions, see the vignettes page.
