List.mean code example

Example 1: list mean python

# Python program to get average of a list

def Average(lst): 
	return sum(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

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: mean of a list python

import numpy as np
np.mean(list)
np.std(list)
