Ok, that's important.

A graphical representation may be useful, but it must be acurate too - else people may incorrectly deduce that something can't be done because it's not expressed in the graph. > > Does anyone know a document that describes it > already, because I think > > it is complicated to find this information in the > documentation of > > Python. > > See section 2 "Data Model" and section 3 "Execution > Model" in the Python > Language Reference http://docs.python.org/ref/ > > => > Thank you, it's pretty standard but somewhat > indigestible.

Inner functions are not attributes of the enclosing one, like local variables are not attributes of the enclosing function. -- Gabriel Genellina Los referentes más importantes en compra/ venta de autos se juntaron: Demotores y Yahoo!
