How to Find the Average in Python? The Easiest Way

import statistics

my_list = [1, 2, 3, 4]

list_average = statistics.mean(my_list)

my_set = {1, 2, 3, 4}

set_average = statistics.mean(my_set)

print("The List Average is {}".format(list_average))

print("The Set Average is {}".format(set_average))

The List Average is 2.5
The Set Average is 2.5

import numpy

# create matrix
my_matrix = [[1, 2, 3, 4], [1, 1, 1, 1]]

# axis=1 will find the average for the rows
matrix_rows_average = numpy.mean(my_matrix, axis=1)

# axis=0 will find the average for the columns
matrix_columns_average = numpy.mean(my_matrix, axis=0)

print("The Matrix rows Averages are {}".format(matrix_rows_average))
print("The Matrix Columns Averages are {}".format(matrix_columns_average))

The Matrix rows Averages are [2.5 1. ]
The Matrix Columns Averages are [1.  1.5 2.  2.5]
