These are then in turn passed along the scipy library “optimize.root” function which solves the system, generating a list of branch currents and node voltages.

SciPy is a free and open-source Python library (built on top of Numpy) used for scientific computing and technical computing. SciPy contains modules for optimization, linear algebra, integration, ...

We’ve seen SciPy in some Hackaday contest entries before. You can think of it like Matlab for Python . Just keep in mind, it isn’t an inherent part of Python.
