There are multiple ways to find the average of the list in Python.
Table of Contents
Using sum() and len()
We can use sum() to find sum of list and then divide it with len() to find average of list in Python.
Here is the quick example of the same.
|
1 2 3 4 5 6 7 8 |
def average(listOfIntegers): return sum(listOfIntegers)/len(listOfIntegers) listOfIntegers = [3,2,4,1,5] averge = average(listOfIntegers) print("Average of listOfIntegers:",averge) |
Output:
Average of listOfIntegers: 3.0
Using reduce(), lambda and len()
We can use reduce() and lambda to find sum of list and then divide it with len() of list.
|
1 2 3 4 5 6 7 8 9 10 |
from functools import reduce def average(listOfIntegers): return reduce(lambda x,y: x+y,listOfIntegers)/len(listOfIntegers) listOfIntegers = [3,2,4,1,5] averge = average(listOfIntegers) print("Average of listOfIntegers:",averge) |
Output:
Average of listOfIntegers: 3.0
Using mean()
We can also directly use inbuilt function mean() from statistics module.
|
1 2 3 4 5 6 7 8 9 10 |
from statistics import mean def average(listOfIntegers): return mean(listOfIntegers) listOfIntegers = [3,2,4,1,5] averge = average(listOfIntegers) print("Average of listOfIntegers:",averge) |
Output:
Average of listOfIntegers: 3
That’s all about find average of list in Python.
