how to calculate average in list python code example

Example 1: average value of list elements in python

# Example to find average of list
number_list = [45, 34, 10, 36, 12, 6, 80]
avg = sum(number_list)/len(number_list)
print("The average is ", round(avg,2))

Example 2: average python

import numpy as np
values=[1,10,100]
print(np.mean(values))
values=[1,10,100,np.nan]
print(np.nanmean(values))

Example 3: find average of list python

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)

Example 4: calcutalte average python

# app.py

def averageOfList(num):
    sumOfNumbers = 0
    for t in num:
        sumOfNumbers = sumOfNumbers + t

    avg = sumOfNumbers / len(num)
    return avg


print("The average of List is", averageOfList([19, 21, 46, 11, 18]))

Example 5: python find average of list

# A function that finds an average of a list of numbers

numbers = [1,2,3,4,5,6,7,889,102390143]

def find_average(number_list):

    total = 0

    for number in number_list:
        total += number
    
    average = total / len(number_list)

    print("Your average is:", average)

find_average(numbers)
