Without addressing zip() in particular (as I said before, its current  
API is just fine to me), and while agreeing with the general  
principle of keeping things as simple as they can be, I don't believe  
you have to teach all the ins-and-outs of a particular function,  
class, or module as soon as it's introduced in the tutorial.  It's  
perfectly fine to keep the intro examples short and sweet with a  
footnote saying "go here for more advanced usage".  There's a ton of  
stuff in Python that total beginners just don't need to know right away.
