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
