# Write a Python program to Update each element in tuple list 
 # Python3 code to demonstrate working of
# Update each element in tuple list
# Using list comprehension
  
# initialize list
test_list = [(1, 3, 4), (2, 4, 6), (3, 8, 1)]
  
# printing original list 
print("The original list : " + str(test_list))
  
# initialize add element

# Update each element in tuple list
# Using list comprehension
res = [tuple(j + add_ele for j in sub ) for sub in test_list]
  
# printing result
print("List after bulk update : " + str(res))
