When it is required to find the closest pair to the Kth index element in a tuple, the ‘enumerate’ method can be used along with ‘abs’ method.Below is the demonstration of the same −Example Live Demomy_list = [(5, 6), (66, 76), (21, 35), (90, 8), (9, 0)] print("The list is ... Read More

When it is required to create a list from a given list that have a number and its cube, the list comprehension can be used.Below is the demonstration of the same −Example Live Demomy_list = [32, 54, 47, 89] print("The list is ") print(my_list) my_result = [(val, pow(val, 3)) for ... Read More

When it is required to find the maximum and minimum K elements in a tuple, the ‘sorted’ method is used to sort the elements, and enumerate over them, and get the first and last elements.Below is the demonstration of the same −Example Live Demomy_tuple = (7, 25, 36, 9, 6, 8) ... Read More

When it is required to find the size of a tuple, the ‘sizeof’ method can be used.Below is the demonstration of the same −Example Live Demoimport sys tuple_1 = ("A", 1, "B", 2, "C", 3) tuple_2 = ("Java", "Lee", "Code", "Mark", "John") tuple_3 = ((1, "Bill"), ( 2, "Ant"), (3, "Fox"), ... Read More
