# Write a Python program to Combinations of sum with tuples in tuple list 
 # Python3 code to demonstrate working of
# Summation combination in tuple lists
# Using list comprehension + combinations
from itertools import combinations
  
# initialize list 
test_list = [(2, 4), (6, 7), (5, 1), (6, 10)]
  
# printing original list 
print("The original list : " + str(test_list))
  
# Summation combination in tuple lists
# Using list comprehension + combinations
res = [(b1 + a1, b2 + a2) for (a1, a2), (b1, b2) in combinations(test_list, 2)] 
  
# printing result
print("The Summation combinations are : " + str(res))
