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))

mean of a list python

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

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)

python get average of list

#python3

def average(list): 
    result = sum(list) / len(list) 
    return result 

list = [68,68,71,71,71,75,71,78,91,98,75,71,84]
print(average(list))

python find the average of a list

numbers = [3, 18, 2, 1, 70, 12, 36, 12, 78, 5, 6, 9]

import statistics

print(statistics.mean(numbers))

mean of a list python

l = [15, 18, 2, 36, 12, 78, 5, 6, 9]

# By using the built-in statistics library
import statistics
statistics.mean(l)  # 20.11111111111111

# By defining a custom function
def average(my_list):
  return sum(my_list) / len(my_list)
average(l) # 20.11111111111111

average of a list in function with python

def lol(a):
	x = sum(a)/len(a)
	print(x)
lol([5,7,3,9,4])
