    6769A morphism is a function which satisfies f(uv) = f(u)f(v). Therefore, defining the images on the letters is sufficient. Maybe what you want to implement is something more general (like a substitution). If yes, I think it would be easier to implement as a new Python class in a new file substitution.py, instead of generalizing morphism.py.
