Summation of tuple in list

We are given a list of tuples consisting of integer elements. We need to create a Python program to perform the summation of all elements of each tuple from the list of tuples.

Input:
[(2, 9) ,(5, 6), (1, 3, 4, 8)]

Output:
38

Method 1:

One method to solve the problem is by first creating a map of sum of elements of each tuple in Python. Then sum up all elements of the map which will be our final result.

# Python program to perform summation of tuple 
# in list using sum and map

# Initializing and printing list of tuples
myList = [(2, 9) ,(5, 6), (1, 3, 4, 8) ]
print("The elements of the list are " + str(myList))

# Performing summation of elements of tuples in list
eleSum = sum(map(sum, myList))

print("The sum of all elements is " + str(eleSum))

Output:

The elements of the list are [(2, 9), (5, 6), (1, 3, 4, 8)]
The sum of all elements is 38

Method 2:

To perform this task, first convert the given tuple to a list, and then flatten list element using the map() function, then perform summation of each using the sum() function, and again employ sum() for overall summation of resultant list.

# Python program to perform summation 
# of tuple in list

# Initializing and printing list of tuples
myList = [(2, 9) ,(5, 6), (1, 3, 4, 8) ]
print("The elements of the list are " + str(myList))

# Performing summation of elements of tuples in list
eleSum = sum(list(map(sum, list(myList))))

print("The sum of all elements is " + str(eleSum))

Output:

The elements of the list are [(2, 9), (5, 6), (1, 3, 4, 8)]
The sum of all elements is 38
