To compute a sum we can use the + operator and add values together. Yet, it would be excessively difficult to do that for large lists (imagine if there are 100 values).

Python has a built-in function sum which given a list computes the sum of its elements.

Having 8 floating-point numbers in the input, your task is to print the sum of 8, then the sum of the first 7 elements, then the sum of the first 6, the sum of 5, 4, ..., up to one element.

Tip 1

You can use del to remove the last element after each sum calculation
