Python program to find the sum of elements of a list using lambda function

Here, we will write a Python program to find the sum of elements of a list using lambda function.

Lambda functions in Python are special functions available in python. They are anonymous functions i.e., without any function name. 

Here, we will find the sum of all elements of the list using the lambda function.

Program to find the sum of all elements of the list

# Python program to find the sum of all elements of the list

# function to find the sum of elements of list
def add(data):
    s=0
    for n in data:
        s=s+n
    return s
    
# List of some fibonacci numbers 
fiboList = [0,1,1,2,3,5,8,13,21,34,55]
print("List of fibonacci numbers :",fiboList)

# calling function to add elements of fibonacci list 
listSum = add(fiboList)
print("The sum of all elements is ",listSum)

Output:

List of fibonacci numbers : [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]
The sum of all elements is  143

Program to find the sum of all elements using lambda function

# Python program to find the sum of 
# all elements of the list

from functools import reduce

# List of some fibonacci numbers 
fiboList = [0,1,1,2,3,5,8,13,21,34,55]
print("List of fibonacci numbers :",fiboList)

# using Lambda function to 
# add elements of fibonacci list 
listSum = reduce(lambda a,b:a+b,fiboList)
print("The sum of all elements is ",listSum)

Output:

List of fibonacci numbers : [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]
The sum of all elements is  143
