Adjunto de matriz 3x3 en Python

'''
TL;DR I found no other way to do this better so here is the handmade function for it.

There is no direct way to find adjoint of a matrix.
Also there is no Numpy function that does this kind of thing so you have to go 
a little offroad from here :)
Following is the formula for finding it in Python:-
                  Adj(matrix) = (cofactor(A))Transpose
After hours of research not finding anything, made my own adjoint function with
a little help from a github repo (link attatched in Source).
Hope I have saved your time and you didn't have to go through the trouble that I have suffered for such a simple looking problem.
Thanks Enjoy!
