What is the difference between using range() and a list of values?

The main differences between the two boil down to the difference between greedy and lazy evaluation. With a list, each indexed object takes up some space in memory. Range, however, calculates the next value on the fly, meaning only one object is stored in memory each time. However, this means range has to calculate each successive value, slowing down the processing speed.
