Many times, while working with records, we can have a problem in which we need to change the value of tuple elements. This is a common problem while working with tuples. Let’s discuss certain ways in which N can be divided by Kth element of tuple in list.
Method #1 : Using loop
Using loops this task can be performed. In this, we just iterate the list to change the Kth element by predefined value N in code.
# Python3 code to demonstrate working of # Divide constant to Kth Tuple index # Using loop # Initializing list test_list = [(4, 5, 6), (7, 4, 2), (9, 10, 11)] # printing original list print("The original list is : " + str(test_list)) # Initializing N N = 3 # Initializing K K = 1 # Divide constant to Kth Tuple index # Using loop res = [] for i in range(0, len(test_list)): res.append((test_list[i][0], test_list[i][K] // N, test_list[i][2])) # printing result print("The tuple after dividing N to Kth element : " + str(res)) |
The original list is : [(4, 5, 6), (7, 4, 2), (9, 10, 11)] The tuple after dividing N to Kth element : [(4, 1, 6), (7, 1, 2), (9, 3, 11)]
Method #2 : Using list comprehension
This method is having the same approach as the above method, just reduces lines of code using list comprehension functionality to make code compact by size.
# Python3 code to demonstrate working of # Divide constant to Kth Tuple index # Using list comprehension # Initializing list test_list = [(4, 5, 6), (7, 4, 2), (9, 10, 11)] # printing original list print("The original list is : " + str(test_list)) # Initializing N N = 3 # Initializing K K = 1 # Divide constant to Kth Tuple index # Using list comprehension res = [(a, b // N, c) for a, b, c in test_list] # printing result print("The tuple after dividing N to Kth element : " + str(res)) |
The original list is : [(4, 5, 6), (7, 4, 2), (9, 10, 11)] The tuple after dividing N to Kth element : [(4, 1, 6), (7, 1, 2), (9, 3, 11)]
