## Developing a Hartree-Fock program, a simple Python program and input files

The input file spdata.dat contains the information of all single-particle quantum numbers needed to define this space. In total we have $$40$$ single-particle states labeled by $$n$$, $$j$$, $$l$$ and $$m$$, where $$m$$ is the projection of the total single-particle angular momentum $$j$$. To every set of single-particle quantum numbers there is a unique number $$p$$ identifiying them, meaning that the two-body matrix elements in the file twobody.dat are identified as $$\langle pq \vert \hat{v}\vert rs \rangle$$.

You will need to read these two files and set up arrays which store the matrix elements while running the program.
