  In high energy physics, the standard convention for expressing physical
quantities is natural units. The standard paradigm sets $c = \hbar = \epsilon_0
= 1$ and hence implicitly rescales all physical quantities that depend on unit
derivatives of these quantities. We introduce $\texttt{NatPy}$, a simple Python
module that defines user-friendly unit objects that can be used and converted
within any predefined system of natural units. In this note, we will first
introduce, then overview, the algebraic methods utilised by the
$\texttt{NatPy}$ module.
