Python problem

Create your own algorithm to fit a third degree polynomial. Write your own python code to do the fit and display it.

You have to solve a set of linear equations in 4 unknowns, where the coefficients of the unknowns depend on the data you create and use

Compare your algorithm to numpy library fit and outline the differences.
