When it is required to convert a nested tuple into a customized key dictionary, the list comprehension can be used.Below is the demonstration of the same −Example Live Demomy_tuple = ((6, 'Will', 13), (2, 'Mark', 15), (9, 'Rob', 12)) print("Thw tuple is : ") print(my_tuple) my_result = [{'key': sub[0], 'value': sub[1], 'id': sub[2]}    for sub in my_tuple] print("The converted dictionary is : ") print(my_result)OutputThw tuple is : ((6, 'Will', 13), (2, 'Mark', 15), (9, 'Rob', 12)) The converted dictionary is : [{'key': 6, 'value': 'Will', 'id': 13}, {'key': 2, 'value': 'Mark', 'id': 15}, {'key': 9, 'value': 'Rob', ...

When it is required to flatten tuple of a list to tuple, a method is defined, that takes input as tuple.The tuple is iterated over, and the same method is called on it over and over again until the result is obtained.Below is the demonstration of the same −Example Live Demodef flatten_tuple(my_tuple):    if isinstance(my_tuple, tuple) and len(my_tuple) == 2 and not isinstance(my_tuple[0], tuple):       my_result = [my_tuple]       return tuple(my_result)    my_result = []    for sub in my_tuple:       my_result += flatten_tuple(sub)    return tuple(my_result) my_tuple = ((35, 46), ((67, ...

When it is required to order the tuples using an external list, the list comprehension, and ‘dict’ method can be used.Below is the demonstration of the same −Example Live Demomy_list = [('Mark', 34), ('Will', 91), ('Rob', 23)] print("The list of tuple is : ") print(my_list) ordered_list = ['Will', 'Mark', 'Rob'] print("The ordered list is :") print(ordered_list) temp = dict(my_list) my_result = [(key, temp[key]) for key in ordered_list] print("The ordered tuple list is : ") print(my_result)OutputThe list of tuple is : [('Mark', 34), ('Will', 91), ('Rob', 23)] The ordered list is : ['Will', 'Mark', 'Rob'] The ordered tuple list is ...

When it is required to remove the tuples of a specific length ‘K’, list comprehension can be used.Below is the demonstration of the same −Example Live Demomy_list = [(32, 51), (22, 13 ), (94, 65, 77), (70, ), (80, 61, 13, 17)] print("The list is : " ) print(my_list) K = 1 print("The value of K is ") print(K) my_result = [ele for ele in my_list if len(ele) != K] print("The filtered list is : ") print(my_result)OutputThe list is : [(32, 51), (22, 13), (94, 65, 77), (70, ), (80, 61, 13, 17)] The value of K is ...

Python tuples are immutable sequences that used to store collections of items. When working with two tuples, you may sometimes need to generate all possible pairs, where each pair contains one element from the first tuple and one from the second. In this article, we will learn different ways to generate all pair combinations from two tuples Following are input-output scenarios for pairing combinations of two tuples: Input: first_tuple = (1, 3) second_tuple = (7, 9) Output: [(1, 7), (1, 9), (3, 7), (3, 9), (7, 1), (7, 3), (9, 1), (9, 3)] Explanation: At index 0 of first_tuple pairs ...

When it is required to extract digits from a list of tuple, list comprehension can be used.Below is the demonstration of the same −Example Live Demomy_list = [(67, 2), (34, 65), (212, 23), (17, 67), (18, )] print("The list is : ") print(my_list) N = 2 print("The value of N is ") print(N) my_result = [sub for sub in my_list if all(len(str(ele)) == N for ele in sub)] print("The extracted tuples are : " ) print(my_result)OutputThe list is : [(67, 2), (34, 65), (212, 23), (17, 67), (18, )] The value of N is 2 The extracted tuples ...

When it is required to join tuples if they contain a similar initial element, a simple ‘for’ loop and an ‘of’ condition can be used. To store elements to one list, the ‘extend’ method can be used.Below is the demonstration of the same −Example Live Demomy_list = [(43, 15), (66, 98), (64, 80), (14, 9), (47, 17)] print("The list is : ") print(my_list) my_result = [] for sub in my_list:    if my_result and my_result[-1][0] == sub[0]:       my_result[-1].extend(sub[1:])    else:       my_result.append([ele for ele in sub]) my_result = list(map(tuple, my_result)) print("The extracted elements ...

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 : ") print(my_list) my_tuple = (17, 23) print("The tuple is ") print(my_tuple) K = 2 print("The value of K has been initialized to ") print(K) min_diff, my_result = 999999999, None for idx, val in enumerate(my_list):    diff = abs(my_tuple[K - 1] - val[K - 1])    if diff ...

In Python, both tuples and lists are used to store data in sequence. Python provides built-in functions and operators that allow us to easily add elements of a tuple into a list and elements of a list into a tuple. In this article, we will explain various methods to perform these conversions, along with example codes. Scenario 1 You are given a list and a tuple as input, your task is to add tuple into the list and print the list as output. For example: # Input List and Tuple my_list = [3, 6, 9, 45, 66] my_tup = ... 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 val in my_list] print("The result is ") print(my_result)OutputThe list is [32, 54, 47, 89] The result is [(32, 32768), (54, 157464), (47, 103823), (89, 704969)]ExplanationA list is defined, and is displayed on the console.The list comprehension is used to iterate through the list, and use the ‘pow’ method to get ...
