In ps3 problem 2, you are asked to return a tuple of the postions a key string matches a target string. My first thought was to add each postion to the tuple every time a postion was found. However, the python wiki book states that you can not add to a tuple (http://en.wikibooks.org/wiki/Python_Programming/Sequences)

Since the lecturer seems to get lists and tuples mixed up a lot, is it possible that the question is wrong?

The other option I can think of would be to assign each postion to a variable 1st then declare them as a tuple at the end, this seems silly if you dont know how many answers there will be.

 Unless you make a list and then declare that list as a tuple at the end??
