print(type("foo") + "foo") Syntactically correct. Will provoke error during runtime due to invalid semantics.

  That's a TypeError though, not undefined behaviour. People are talking about different things.

    True. But I was answering this specific to the question of "syntactically valid yet semantically invalid statements" in python.
