Assuming the database to be an array of ten (8) books, construct a class called Books with relevant data members and member functions that will allow one to:- (i) Insert a new book record into the database (ii) Display a list of all books in the database (iii) Write a main function to test the program

get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary.

The following are your requirements: make_dict(n) Write a function called make_dict(n), where n is an integer parameter. With a given number n, make a new dictionary in your function where the keys in the dictionary are in the range from 1 to n, and value for each key is the square of the key for that entry. Your function should return this dictionary, not print it. main() Call make_dict(n), where the user is asked to specify a number to pass into make_dict(n), and then prints the returned dictionary object.

Define the function lake_to_tli3_dict(readings) that takes a list of (lake_name, chla, tn, tp) tuples and returns a dict mapping lake names to trophic level index values. That is, the keys are lake names and the values will be TLI3 values. Notes: You will need to have import math as your first line of code. You must include and use/call the trophic_level_index function that you wrote in Question 1. trophic_level_index must still work as specified in Question 1. Lakes should be added to the dictionary in the same order as they appear in the readings list. If a lake appears in the readings list more than once, then the TLI for the last occurrence in the readings list should be the one that appears in the result. (This should happen naturally, since the lake name can only occur in the dictionary once.) For example: Test Result names_cnp_1 = [('Lake Brunner', 0.8, 218.0, 6.0), ('Lake Carrot', 5.1, 505.0, 18.5) ] tli3_dict = lake_to_tli3_dict(names_cnp_1 ) print(tli3_dict)…

Best Practices to Follow: It’s worth breaking up each functional task in create_blackjack_game() into separate functions. For example, a function to check the score of a player’s hand, to check whether a player has won, and so on. This entire implementation can be done neatly in about eight functions. Create a Deck of Cards Complete the create_standard_deck() function, which creates a new deck. The deck itself must be a data structure list. The cards within the deck must be represented as tuples of the form (suit, number), where the suit is a string that must be either ‘hearts’, ‘clubs’, ‘spades’, or ‘diamonds’, and the number is an integer that must be one of the following: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14. Note that the number used to identify the card has the following association: Jack = 11, Queen = 12, King = 13, and Ace = 14. In terms of value, the picture cards (Jack, Queen, and King) all have a value of 10, and the Ace card has a value of 11. The casino only wants…
