Message: [QUOTE="Roy Smith, post: 5093536"] Hmmm, homework for a class? I suspect what you're trying to say is that bananas cost BTC 4 each, and since you've got 6 bananas, you've got BTC 24 worth of bananas, yes? And now you want to find the total value of your fruit supply? So far, so good. A couple of things you may have noticed along the way: 1) Your orange unit price was a float, so the total value of all your oranges is a float as well. That's how math works in Python. 2) The keys are presented in random order. To make the output easier to interpret, you might want to do: print key, prices[key]*stock[key] The most straight-forward way would be something like: total = 0 for key in prices: fruit_subtotal = prices[key]*stock[key] total += fruit_subtotal print key, fruit_subtotal print total There are better ways to do this in Python, but start like this and get that to work.
