Finding mean of a values in a dictionary without using .values() etc

Question

I have a dictionary that looks like:

G={\'E\': 18.0, \'D\': 17.0, \'C\': 19.0, \'B\': 15.0, \'A\': 0}

I have to find the mean of the values

Answer 1

In Python 3.4 upwards there is a very clear way:

import statistics
numbers = [G[key] for key in G]
mean_ = statistics.mean(numbers)
