I can't tell you how many times I've gotten bit in the ass with that off-by-one mistake whenever I use a range that doesn't start at zero.

I know that if I want to loop 10 times and I either want to start at zero or just don't care about the actual number, I use `for i in range(10)`.  But if I want to loop from 10 to 20, my first instinct is to write `for i in range(10, 20)`, and then I'm left figuring out why my loop isn't executing the last step.
