min_max_avg(numbers) that returns a tuple (minimum, maximum, average) for a non-empty list of numbers, where average is a float. Demonstrate that a caller can unpack this into three separate variables in one line.min_max_avg([4, 8, 2, 10])
(2, 10, 6.0)
min=2, max=10, avg=(4+8+2+10)/4=6.0.
min_max_avg([5])
(5, 5, 5.0)
Single-element list: all three stats equal 5.
Use built-in min(), max() and sum()/len().
Return the three values as a tuple literal, e.g. `(lo, hi, avg)`.
