It's possible to install Python and NumPy separately, however ... you multiply each input value times its associated input-to-hidden weight, add the products up, then add the bias value, and then ...

What is NumPy? NumPy is a fundamental package for scientific computing, widely used by Python developers. Underneath the Python API, it performs computations in C or Fortran to help speed up Python.

Additionally, both libraries make extensive use of the "numerical Python" (NumPy) add-in package to create vectors and matrices, which typically offer better performance than Python's built-in list ...
