When it is required to delete a node from the middle of the circular linked list, a 'Node' class needs to be created. In this class, there are two attributes, the data that is present in the node, and the access to the next node of the linked list.In a circular linked list, the head and the rear are adjacent to each other. They are connected to form a circle, and don't have 'NULL' value in the last node.Another class needs to be created that would have an initialization function, and the head of the node would be initialized to ...

When it is required to create a circular linked list and display it, a 'Node' class needs to be created. In this class, there are two attributes, the data that is present in the node, and the access to the next node of the linked list. In a circular linked list, the head and the rear are adjacent to each other. They are connected to form a circle, and don't have 'NULL' value in the last node.Another 'linked_list' class needs to be created that would have an initialization function, and the head of the node would be initialized to 'None'.

When it is required to create a circular linked list and display it in the reverse order, a 'Node' class needs to be created.To display the data elements in the circular list in reverse order, another method can be defined, that would reverse the data. In this class, there are two attributes, the data that is present in the node, and the access to the next node of the linked list. In a circular linked list, the head and the rear are adjacent to each other. They are connected to form a circle, and don't have 'NULL' value in the ... Read More
When it is required to create a circular linked list that has 'N' nodes, and get the count of the number of nodes, a 'Node' class needs to be created. To display the data elements in the circular list, another method can be defined, that would display the data. In this class, there are two attributes, the data that is present in the node, and the access to the next node of the linked list. In a circular linked list, the head and the rear are adjacent to each other.They are connected to form a circle, and don't have 'NULL' ... Read More
When it is required to shuffle a deck of cards using Python, the 'itertools' and the 'random' packages need to be used. Random library has a method named 'shuffle' that can be used to mix up and show the data.Below is a demonstration for the same −ExampleLive Demoimport itertools, random my_deck = list(itertools.product(range(1, 11), ['Spade', 'Heart', 'Diamond', 'Club'])) print("The cards are being shuffled") random.shuffle(my_deck) print("Cards are drawn at random") print("They are : ") for i in range(5): print(my_deck[i][0], "of", my_deck[i][1])OutputThe cards are being shuffled Cards are drawn at random They are : 1 of Diamond 5 of Diamond 4 ...

When it is required to create a Python program that generates a linked list, a 'Node' class needs to be created. To display the data elements in the circular list, another method can be defined, that would display the data. In this class, there are two attributes, the data that is present in the node, and the access to the next node of the linked list. In a circular linked list, the head and the rear are adjacent to each other. They are connected to form a circle, and don't have 'NULL' value in the last node.Another 'linked_list' class needs ...

When it is required to sort the list of tuples in a specific order, the 'sorted' method can be used.The 'sorted' method is used to sort the elements of a list.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 Demodef tuple_sort(my_tup): return(sorted(my_tup, key = lambda x: x[1])) my_tuple = [('Mahe', 11), ('Aisha', 33), ('Will', 50), ('Root', 65)] print("The list of tuple is : ") print(my_tuple) ...

When it is required to remove a tuple from a list of tuples based on a given condition, i.e the tuple doesn't contain a specific character, 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 = [('. ', 62), ('Mark', 5), ('Paul.', 21), ('.....', 0), ... Read More
When it is required to remove tuples from a list of tuples if it is greater than a value 'n', the lambda function can be used.Anonymous function is a function which is defined without a name. In general, functions in Python are defined using 'def' keyword, but anonymous function is defined with the help of 'lambda' keyword.It takes a single expression, but can take any number of arguments. It uses the expression and returns the result of it.Below is a demonstration for the same −ExampleLive Demomy_tuple = [('a', 130), ('b', 230), ('c', 25), ('z', 654), ('f', 69)] print("The list ...
