Python package for handling numpy arrays with units

 Often writing code that deals with data that has units can be
 confusing. A function might return an array but at least with plain
 NumPy arrays, there is no way to easily tell what the units of the
 data are without somehow knowing a priori.
 .
 The unyt package (pronounced like “unit”) provides a subclass of
 NumPy’s ndarray class that knows about units.
