Suppose I have functions f, g1, g2, h and an operation , which is not necessarily multiplication, satisfying the following relations:

f(XY)=g1(X)g2(Y)+g1(Y)g2(X)+f(X)f(Y)+h(XY)

h(XY)=h2(X)g1(Y)

How to find a symbolic expression for f(X7)?

I don't understand your question; f(X*Y) = ... does not seem to be valid Python syntax. Could you provide the full code of what you are trying to do?

Define f(X*Y) as a function with 2 arguments, say f2(X,Y), and then compute f(X^7) recursively as f2(X,f2(X,f2(X,f2(X,f2(X,f2(X,f2(X,X)))))).
