Why are these homework programming challenges so recognisable? It boils down to: Write a function that that uses X and Y techniques. The function may be hard and challenging to write but doesn't ever do anything interesting or anything that is useful and complete on its own.
I realise teachers have to test mastery of certain techniques, but they seem to lack the imagination. Especially with modern languagues like Python, where you can write a whole program that actually does something usefull using only a few lines of code it should not be necessary to ask these kinds of dull questions. Just stick at it Natasha, it is far more interesting when you the programming challenge has to accomplish a real result.
