# Python program to get average of a listdefAverage(lst):returnsum(lst)/len(lst)# Driver Code
lst =[15,9,55,41,35,20,62,49]
average = Average(lst)# Printing average of the list print("Average of the list =",round(average,2))# Output:# Average of the list = 35.75
list=[15,18,2,36,12,78,5,6,9]# for older versions of python
average_method_one =sum(list)/len(list)# for python 2 convert len to a float to get float division
average_method_two =sum(list)/float(len(list))# round answers using round() or ceil()print(average_method_one)print(average_method_two)
l =[15,18,2,36,12,78,5,6,9]# By using the built-in statistics libraryimport statistics
statistics.mean(l)# 20.11111111111111# By defining a custom functiondefaverage(my_list):returnsum(my_list)/len(my_list)
