Does Sage support tensor of two symmetric functions?

I want to work in two variables symmetric functions. For example, expand $h_\lambda(X+Y)$ or $h_\lambda(X) e_\mu(Y)$ to $s_\lambda(X) s_\mu(Y)$.

Have you searched the documentation?

Ideally, provide code to define the objects in your question, to get answerers started.

Here is a start

sage: S=SymmetricFunctions(QQ).s()                                              
sage: S([4]).tensor(S([3]))                                                     
s[4] # s[3]

Thank you. I know this method.

Could you expand the question a little bit, to say how what you are looking for differs from what is found in the documentation?
