When trying to understand a function (or in this case, a generator), knowing the types of input and output can be helpful. Also, knowing some sample outputs for small inputs is also important. Without even looking at the implementation, can you say in words what this function is intended to do? What's the type of the input? What's the type of the output? And can you give a few concrete examples of what you'd like it to do on "small" inputs? (Trying to demonstrate a general problem strategy that works surprisingly well, and that we actually use in practice.) _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
