NLTK Tutorial: Parsing • The left-hand side is a single non-terminal, which may be any Python object. In the simplest case it is just a string (e.g. "NP" or "VP"). • The right-hand side is a tuple of non-terminals and terminals, which may be any Python object. In the simplest case these are strings (e.g. "Det", "the").
