Media aritmetica

La media aritmetica di 2 (3) valori numerici

def media2(x, y): return (x+y)/2

def media3(x, y, z): return (x+y+z)/3

a=18

b=19

c=28

... media2(a, b) # 18.5

... media2(a, c) # 23.0

... media2(b, c) # 23.5

... media3(a, b, c) # 21.67

import math

def media2g(x, y): return math.sqrt(x*y)

def media3g(x, y, z): return math.pow(x*y*z, 1/3)

a=18

b=19

c=28

... media2g(a, b) # 18.49

... media2g(a, c) # 22.45

... media2g(b, c) # 23.065

... media3g(a, b, c) # 21.235
