Python | Addition of tuples
  • Last Updated : 11 Nov, 2019

Sometimes, while working with records, we might have a common problem of adding contents of one tuple with corresponding index of other tuple. This has application in almost all the domains in which we work with tuple records. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using map() + lambda
Combination of above functionalities can solve the problem for us. In this, we compute the summation using lambda functions and extend the logic to keys using map().




# Python3 code to demonstrate working of
# Addition of tuples
# using map() + lambda
  
# initialize tuples 
test_tup1 = (10, 4, 5)
test_tup2 = (2, 5, 18)
  
# printing original tuples 
print("The original tuple 1 : " + str(test_tup1))
print("The original tuple 2 : " + str(test_tup2))
  
# Addition of tuples
# using map() + lambda
res = tuple(map(lambda i, j: i + j, test_tup1, test_tup2))
  
# printing result
print("Resultant tuple after addition : " + str(res))
Output :
The original tuple 1 : (10, 4, 5)
The original tuple 2 : (2, 5, 18)
Resultant tuple after addition : (12, 9, 23)

 

Method #2 : Using map() + zip() + sum()
The combination of above functions can also be used to achieve this particular task. In this, we add inbuilt sum() to perform summation and zip the like indices using zip() and extend logic to both tuples using map().






# Python3 code to demonstrate working of
# Addition of tuples
# using map() + zip() + sum()
  
# initialize tuples 
test_tup1 = (10, 4, 5)
test_tup2 = (2, 5, 18)
  
# printing original tuples 
print("The original tuple 1 : " + str(test_tup1))
print("The original tuple 2 : " + str(test_tup2))
  
# Addition of tuples
# using map() + zip() + sum()
res = tuple(map(sum, zip(test_tup1, test_tup2)))
  
# printing result
print("Resultant tuple after addition : " + str(res))
Output :
The original tuple 1 : (10, 4, 5)
The original tuple 2 : (2, 5, 18)
Resultant tuple after addition : (12, 9, 23)
