find the mean of a list in 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: 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 3: 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]))
