Python program to perform pairwise addition in tuples

Method 1:

In this method, we will return the sum of pairs of an element of the tuple and the element next to it. The pair sum is done using a generator function and the pairing of neighbouring elements is done using zip() method. All these pair sum values are added to a tuple which is our result.

# Python program to perform pairwise 
# addition in tuples
  
# Initializing and printing tuple 
myTuple = (3, 1, 7, 9, 2)
print("The elements of tuple are " + str(myTuple))
  
# Performing pairwise addition operation on tuples
additionTuple = tuple(i + j for i, j in zip(myTuple, myTuple[1:]))
  
# Printing result 
print("The pairwise added elements in tuple are " + str(additionTuple))

Output:

The elements of tuple are (3, 1, 7, 9, 2)
The pairwise added elements in tuple are (4, 8, 16, 11)

Method 2:

One more implementation of the solution is by using the create a map where each element is created using a lambda function which will take the sum of the current and next element of the sum. Then the map with additional pairs is then converted using tuple().

# Initializing and printing tuple 
myTuple = (3, 1, 7, 9, 2)
print("The elements of tuple are " + str(myTuple))
  
# Performing pairwise addition operation on tuples
additionTuple = tuple(map(lambda i, j : i + j, myTuple[1:], myTuple[:-1]))
  
# Printing result 
print("The pairwise added elements in tuple are " + str(additionTuple))

Output:

The elements of tuple are (3, 1, 7, 9, 2)
The pairwise added elements in tuple are (4, 8, 16, 11)
