I've gotten the pig latin question in week 4, but am having problems with the Report Card GPA and the 2nd and 3rd List comprehension - has anyone done these yet? Any hints?

    i think something like: def f(word): # create a list of vowels v = 'aeiouy' # since working on comprehensions... vowels = [v[x] for x in range(len(v))] l = [word[x] for x in range(len(word)) if word[x] in vowels] return l f('the rather slothful brown fox stepped over the line') ['e', 'a', 'e', 'o', 'u', 'o', 'o', 'e', 'e', 'o', 'e', 'e', 'i', 'e'] outcomes = [[x,y] for x in ['h','t'] for y in ['h','t']] print outcomes [['h', 'h'], ['h', 't'], ['t', 'h'], ['t', 't']]

    Thanks - I'm getting better with the comprehension lists. I'm still unsure of what to do with the GPA problem, I'll tackle that tomorrow. Appreciate all your help.

    I'm on the GPA problem also. Like many of the exercises, it is very poorly written. It should have been peer reviewed, and student critiqued. "Could we write the program in a different way" Is this part of the exercise? "There are a couple ways to do this" Really? How about if we find just one? I think the exercise is simpler than it appears once you weed out the confusing verbage.Thats my guess at any rate. I'll know once I finish the exercise.

    Thanks pdpinch - that was helpful. I'm still having trouble with how to approach these, I guess it's just me trying to figure out how to program well - my brain isn't clicking with it as easily as I would like :/
