Daily sign-ups jump around a lot. A moving average smooths them by averaging each run of k days in a row.
Write a function moving_average(values, k) that returns the average of every run of k values in a row, each rounded to 2 decimals. A list of n values gives n - k + 1 averages, and if the list is shorter than k the answer is empty.
How it's checked
Your code runs, then the check below runs and its printed output is compared with ours.
moving_average([1, 2, 3, 4], 2) returns [1.5, 2.5, 3.5]Hints, the later steps and the answer come with Pro.
