List & for LoopList & for Loop

We can employ various data structures when working with loops. So far, we've covered strings, and now we'll explore working with a list of numbers.

Examine the following code:

How does the code work?

To work with a decreasing list, you can utilize the reversed() function. This function allows you to reverse the order of elements in a list, effectively turning it into a decreasing list.

How does the code work?

Task

To sum the elements inside the list, follow these steps:

  1. Configure the for loop to operate on the numbers, utilizing i as an element of the list.
  2. Calculate the sum by adding elements to the counter within the loop.
  3. Print the value of the counter after the loop has completed.
