You simply call it.

Your main problem: resolve the "id" into an object.
For this, you should either pass a namespace or an object
as parameter to the first method.
If you use a namespace "ns", you access "id" by "ns[id]",
for an object "o", you would use "getattr(o,id)".

Once you have the method corresponding to "id", you simply
call it.
