LAB ASSIGNMENTS IMPORTANT: you should complete the PDP thinking process for each program. Turn in items: 1) book_list.py: you can adapt your Chapter 4 book_list.py Lab program. The program summarizes costs of a book list. It uses all of our standard mipo_ex features. In this version of the program you must use pylnputPlus functions to perform all the input validation and for the main() loop decision. Adjust your program to allow book prices to include $ and cents. Restrict individual book prices to $100 maxium. • Clearly document, with comments, your use of the pyip functions. This program summarizes a book liat.

Task 2: Using Function-Temperature Table The formula for converting a temperature from Fahrenheit to Celsius is: 5 C = (F-32) Where F is the Fahrenheit temperature and C is the Celsius temperature. Write a function named Celsius that accepts a Fahrenheit temperature as an argument. The function should return the temperature, converted to Celsius. Demonstrate the function by calling it in a loop that displays a table of Fahrenheit temp. 0 through 20 and there Celsius equivalents. The program should display the number of numbers found in the file, the sum of the numbers, and the average of the numbers.

JS You are writing a number guessing program where the player must try to guess the secret number 17. This function will take a player's guess and tell them if they are either right or whether they should guess higher or lower on their next turn Write a function named "higher_lower" that takes an int as a parameter and returns "higher" if 17 is greater than the input and "lower" if 17 is less than the input, and "correct" if 17 is equal to the input.
Add distribution function in code The system should allow the employees to list all distributed vaccines and their accumulated quantities read from the dist. txt file. Note: The vaccines and their distributed quantities need to be sorted in descending order (with highest quantity listed first followed by second highest and so on) using Bubble sort before displaying on the screen. MY C Programming CODE: #include <stdio.h> #include <stdlib.h> #include <string.h> // Function Declarations void create_inventory(); void update_vacc_qty(); int search_vaccine(); void display_vaccine(); // Main Function starts here int main() { create_inventory(); display_vaccine(); search_vaccine(); //update_vacc_qty(); return 0; } //Function to Create Vaccine.txt as per the given table void create_inventory() { int option = 1; // variables to collect data as per table given char vaccName[15]; char vaccCode[2]; char country[15]; int qty; float populaion; //File definition FILE *infile;…
Jacobsthal numbers are an integer sequence, where the nth Jacobsthal number can be defined as follows: 0 -- {₁-1+2√₁ Jn=" if n = = 1; if n = 2; Jn-1+2Jn_2 if n>2. Complete the print_jacobsthal_numbers () function that takes an integer parameter number_of_terms specifying the number of Jacobsthal numbers the function needs to print. You can assume that number_of_terms will always be an integer that is 1 or more. The function should print the specified number of Jacobsthal numbers on a single line with each Jacobsthal number separated by a ", ". Some examples of the function being called are shown below. For example: Test Result print_jacobsthal_numbers (3) 0, 1, 1 print_jacobsthal_numbers (5) 0, 1, 1, 3, 5 Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %) Reset answer 1 def print_jacobsthal_numbers(number_of_terms): ▼
