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_sumwithgrades_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.
