If you iterate over a dictionary, it will iterate over just the keys, not key-value tuples. You want to say "for name in array:" and then "print array[name]" and so forth. Alternatively, you could say "for (name, item) in array.items():" and then the rest of your code would work the way you want it to, since the dict.items method
does return key-value tuples. The first way is more efficient, though.
EDIT: You can actually accomplish all of this much more efficiently and with a
lot less code. Try this:
- def average(array):
-
return float(sum(array.values())) / len(array)
