Python – Sum of tuple elements

  • Last Updated : 19 Feb, 2020

Sometimes, while programming, we have a problem in which we might need to perform summation among tuple elements. This is an essential utility as we come across summation operation many times and tuples are immutable and hence required to be dealt with. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using list() + sum()
The above functions can be combined to perform this task. We can employ sum() to accumulate the result of summation logic. The list() function is used to perform interconversions.




# Python3 code to demonstrate working of 
# Tuple summation
# Using list() + sum()
  
# initializing tup 
test_tup = (7, 8, 9, 1, 10, 7
  
# printing original tuple
print("The original tuple is : " + str(test_tup)) 
  
# Tuple elements inversions
# Using list() + sum()
res = sum(list(test_tup))
  
# printing result 
print("The summation of tuple elements are : " + str(res)) 
Output :
The original tuple is : (7, 8, 9, 1, 10, 7)
The summation of tuple elements are : 42

 

Method #2 : Using map() + sum() + list()
The combination of above functions can be used to perform this task. In this, we first convert the tuple to list, flatten it’s each list element using map(), perform summation of each using sum() and again employ sum() for overall summation of resultant list.






# Python 3 code to demonstrate working of 
# Tuple elements inversions
# Using map() + list() + sum()
  
# initializing tup 
test_tup = ([7, 8], [9, 1], [10, 7]) 
  
# printing original tuple
print("The original tuple is : " + str(test_tup)) 
  
# Tuple elements inversions
# Using map() + list() + sum()
res = sum(list(map(sum, list(test_tup))))
  
# printing result 
print("The summation of tuple elements are : " + str(res)) 
Output :
The original tuple is : (7, 8, 9, 1, 10, 7)
The summation of tuple elements are : 42
