This is a classic mistake. i in your case is already an element from array (i.e. another list), not an index of array (not an int), so You can check the Python tutorial. Also, try doing this: And see what you get! Also I would advise to stick to naming conventions: variables are normally lower-case (volume, not Volume). In this case i is misleading. row or elem would be much more suitable.
As Greg Hewgill said, the typedef means you no longer have to write struct all over the place.

The comment was referring to the Big-O Notation. Briefly: O(1) means in constant time – independent of the number of items. O(N) means in proportion to the number of items. O(log N) means a time proportional to log(N) Basically any ‘O’ notation means an operation will take time up to a maximum of k*f(N)where: k is a … Read more
Use !=. See comparison operators. For comparing object identities, you can use the keyword is and its negation is not. e.g.
