  Numerov's numerical method is developed in a didactic way by using Python in
its {\it Jupyter Notebook} version 6.0.3 for three different quantum physical
systems: the hydrogen atom, a molecule governed by the Morse potential and for
a quantum dot. After a brief introduction to the Numerov method, the complete
code to calculate the eigenfunctions and eigenvalues of the hydrogen atom is
presented. The necessary code changes to calculate the other two examples are
also provided in the sequel.
