You’ll start by using variables in expressions. Then, you’ll dive into counters and accumulators, which are essential for keeping track of values during iteration. You’ll also learn about other common use cases for variables, such as temporary variables, Boolean flags, loop variables, and ...

As you can see, you start off the loop with the for keyword. Next, you make use of a variables index and languages, the in keyword, and the range() function to create a sequence of numbers. Additionally, you see that you also use the len() function in this case, as the languages...
