Yes, I understood alright what you were asking. As I said, I don't
believe there is any more formal documentation of the Python language
than what you have already seen. However, I am of the opinion that it
gives you all the information you need, and that a complete formal
grammar, while perhaps, for you, easier to interpret, would not add any
