Range() in a for Loop 2/2Range() in a for Loop 2/2

Note

In many of our tasks, we'll frequently employ a counter variable to facilitate basic arithmetic operations.

For instance, if we wish to sum 2 and 3, we'll initialize the counter with counter = 0 and then add 2 and 3 to it: counter = 0 + 2 + 3 = 5 => counter = 5.

The utilization of such variables is essential for managing straightforward mathematical operations effectively.

Take a look at the following code:

How does the code work?

Завдання

We've previously seen an example of summing elements from 50 to 100 using an increasing list. Now, let's tackle this task with a decreasing list:

  1. Establish a for loop, utilizing i as an element of the range and setting step = -1.
  2. Execute the summation by adding the elements within the range.
  3. Print the value of the counter.
