# The range as a sequence with `..` and `...`
The range is used to generate a sequence of values. It requires a start point and an endpoint to specify the values. There are two kinds of ranges:
 1. The range specified with `..` generates the values, including the upper limit. For example, `0..100` generates values $0$ to $100$. 





 2. The range specified with `...` generates the values excluding the upper limit. For example, `0...100` generates values $0$ to $99$.

It also makes it easy to specify the increment or jump value using the step function. For example, `10..100.step(2)` generates even values between  $10$ and $100$. 

Learn about fixed iteration loops that have a large number of iterations with different intervals.
