The range function

The range function generates a sequence of integers. It takes from one to three arguments, and each of those is expected to be an integer. If only one is defined, it will be treated as a right-hand limit of the range and will be not included. If two are defined—the first one will be the left-hand limit, and included in the range, while the second will take the role of the right-hand limit. If a third value is specified, it will be used as a step—the default step is equal to 1.

The range function returns a generator—a special type of iterable that computes its values on the fly. That is why, in order to see the actual result, we need to convert it to a list.

Let's look at the following example. Here, we generate a range ...
