bookRange() 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:

12345678
counter = 0 # Summing all numbers from 50 to 100 (included) for i in range(50, 101): counter += i # Printing the counter print(counter)
copy

How does the code work?

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.
