  Multiple software packages currently exist for the computation of bulk
topological invariants in both idealized tight-binding models and realistic
Wannier tight-binding models derived from density functional theory. Currently,
only one package, PythTB(https://www.physics.rutgers.edu/pythtb/) is capable of
computing nested Wilson loops and spin-resolved Wilson loops. These
state-of-the-art techniques are vital for accurate analysis of band topology.
In this paper we introduce BerryEasy, a python package which is built to work
alongside the PyBinding(https://docs.pybinding.site/en/stable/index.html)
software package. By working in tandem with the Pybinding package and
harnessing the speed of graphical processing units, topological analysis of
supercells in the presence of disorder and impurities is made possible. The
BerryEasy package simultaneously accommodates use of realistic tight-binding
models developed using Wannier90.
