Encuentra el promedio de una lista en python

Requisitos previos: función sum() , función len() , función round(), reduce(), lambda y mean() . Dada una lista de números, la tarea es encontrar el promedio de esa lista. El promedio es la suma de los elementos dividida por el número de elementos.

Input : [4, 5, 1, 2, 9, 7, 10, 8]
Output : Average of the list = 5.75
Explanation:
Sum of the elements is 4+5+1+2+9+7+10+8 = 46
and total number of elements is 8.
So average is 46 / 8 = 5.75

Input : [15, 9, 55, 41, 35, 20, 62, 49]
Output : Average of the list = 35.75
Explanation:
Sum of the elements is 15+9+55+41+35+20+62+49 = 286
and total number of elements is 8.
So average is 46 / 8 = 35.75

En Python podemos encontrar el promedio de una lista simplemente usando la función sum() y len() .
