'''
Calling functions

Using the given function which calculates the mean, find the list which has the
highest mean and the value of that mean. Using the function we do not need to 
write the logic of calculating the mean again for every list, but instead we put 
the logic in one function and re-use the same function for every list.

Hint: use a for loop and track the highest mean.
