Computing the Average
The average test grade can be found by dividing the sum of the grades by the total number of grades.
Luckily, we just created an awesome function, grades_sum
to compute the sum.
Instructions
1.
Define a function, grades_average
, below the grades_sum
function that does the following:
- Has one argument,
grades_input
, a list - Calls
grades_sum
withgrades_input
- Computes the average of the grades by dividing that sum by
float(len(grades_input))
. - Returns the average.
Call the newly created grades_average
function with the list of grades
and print the result.
