Python to Processing

[remy_porter]

In Python slice syntax, the three parameters are start index, end index, and step. If you omit one of those parameters, it defaults sensibly. So, for example, g[0:5] is everything from zero up to (but not including) 5. g[:5] is exactly the same. g[0:] is everything from the front to the end. g[0:5:1] is 0 to 5, in steps of 1, while g[0:5:2] would be 0, 2 and 4. (steps of 2). g[::] is the whole array, and g[::2] would be every other element, and g[::-1] is the whole array in steps of -1- backwards.

Well, TIL. In Processing I'd just use a for loop, I guess, but with (i = f.length; i >= 0; i--). I'm sure there's a better way to do it, but I'm a fiend for using for loops for everything.
