When it is required to modify the list of tuple, the 'zip' method and the list comprehension can be used.The zip method takes iterables, aggregates them into a tuple, and returns it as the result.The list comprehension is a shorthand to iterate through the list and perform operations on it.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on). A list of tuple basically contains tuples enclosed in a list.Below is a demonstration for the same −ExampleLive Demomy_list_1 = [('Hi', 1), ('there', 2), ('Jane', 3)] my_list_2 = ... Read More

When it is required to remove tuples that have a duplicate first value from a given set of list of tuples, a simple 'for' loop, and the 'add' and 'append' methods can be used.Below is a demonstration for the same −ExampleLive Demomy_input = [(45.324, 'Hi Jane, how are you'), (34252.85832, 'Hope you are good'), (45.324, 'You are the best.')] visited_data = set() my_output_list = [] for a, b in my_input:    if not a in visited_data:       visited_data.add(a)       my_output_list.append((a, b)) print("The list of tuple is : ") print(my_input) print("The list of tuple after ...

When it is required to unpack a tuple of list, the 'reduce' method can be used. A tuple is an immutable data type. It means, values once defined can't be changed by accessing their index elements. If we try to change the elements, it results in an error. They are important contains since they ensure read-only access.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).A tuple of list contains multiple lists, which are enclosed in '(' and ')'.The 'reduce' method is used to apply a specific ...

When it is required to remove the matching tuples from two list of tuples, the list comprehension can be used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).A list of tuple basically contains tuples enclosed in a list.The list comprehension is a shorthand to iterate through the list and perform operations on it.Below is a demonstration for the same −ExampleLive Demomy_list_1 = [('Hi', 'there'), ('Jane', 'Hi'), ('how', 'are'), ('you', '!')] my_list_2 = [('Hi', 'there'), ('Hi', 'Jane')] print("The first list is : ") print(my_list_1) print("The second ...

When it is required to sort the tuple based on the occurrence of the first element, the dict.fromkeys method can be used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).A list of tuple basically contains tuples enclosed in a list.The 'dict.fromkeys' method will return a dictionary with a specific key and a value.Below is a demonstration for the same −ExampleLive Demodef sort_on_occurence(my_lst):    my_dict = {}    for i, j in my_lst:       my_dict.setdefault(i, []).append(j)    return([(i, *dict.fromkeys(j), len(j))       for i, ...

When it is required to get the summation of a list of tuple, the list comprehension and the 'sum' method can be used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).A list of tuple basically contains tuples enclosed in a list.The list comprehension is a shorthand to iterate through the list and perform operations on it.The 'sum' method is used to add the elements of an iterable, where the iterable is passed as an argument to the method.Below is a demonstration for the same −ExampleLive Demomy_list ...

When it is required to find the grouped summation of a list of tuple, the 'Counter' method and the '+' operator need to be used.The 'Counter' is a sub-class that helps count hashable objects, i.e it creates a hash table on its own (of an iterable- like a list, tuple, and so on) when it is invoked.It returns an itertool for all of the elements with a non-zero value as the count.The '+' operator can be used to add numeric values or concatenate strings.Below is a demonstration for the same −ExampleLive Demofrom collections import Counter my_list_1 = [('Hi', 14), ...

When it is required to reverse each tuple in a list of tuples, the negative step slicing can be used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on). A list of tuple basically contains tuples enclosed in a list.In negative slicing, the index is accessed using negative numbers, instead of positive ones.Below is a demonstration for the same −ExampleLive Demodef reverse_tuple(my_tuple):    return [tup[::-1] for tup in my_tuple]           my_list = [(21, 22), (43, 74, 45), (76, 17, 98, 19)] print("The list ...

When it is required to check if a string is symmetrical or it is a palindrome, a method can be defined, that uses the ‘while’ condition. Another method is defined to check the symmetry that uses the ‘while’ and ‘if’ conditions too.A palindrome is a number or string, which when read from left to right or right to left is the same value. The index values are the same.ExampleBelow is a demonstration for the same − Live Demodef check_palindrome(my_str):    mid_val = (len(my_str)-1)//2    start = 0    end = len(my_str)-1    flag = 0    while(start
