Find average rating of the ice-cream

Problem Statement

The company ABC has online ice-cream store. The company has released a new ice-cream and wants to know the average rating of this ice-cream. The company receives the ratings of the ice-cream on a scale of 1 to 5 from its customers.

Input

The first line of input is ratings, space separated integer values (each rating is 1, 2, 3, 4, or 5), where each value represents the rating for the new ice-cream by a customer.

Output

Print the average rating of the ice-cream.

As is

The boilerplate code is already there to read the input from user, in the main() function, and to print the value returned by the get_average_rating() function. Do not edit this code.

To do ✍

get_average_rating() has one parameter: ratings that is a list. Write code inside the function body to find the average of the ratings, and return the average value (a float rounded to a single digit after the decimal point).

Example 1

Test input

4 3 4 4 3 4 5

Test output

3.9

Explanation

Average = Sum of ratings / number of ratings
        = (4 + 3 + 4 + 4 + 3 + 4 + 5) / 7
        = 27 / 7
        = 3.857
        = 3.9 (rounded to a single decimal point)
