LAB ASSIGNMENT, CONT. 2) author_book.py Use the previous project as a model. This time, use a variable called readings, of the dictionary data type (instead of users). It stores your favorite authors and book titles, as key-value pairs. Initialize the dictionary with 3 authors and book titles. Like the previous program, this one should display a command menu and let the user view, add, edit and delete dictionary entries. With the new program, you need to adapt the variable names, user-facing messages and capitalization strategies to fit the new content. NOTE: test data needs to use the same capitalization strategy as the program. COMMAND MENU view - View readings add Add a reading edit del exit Edit a reading Delete a reading Exit program Command: edit Enter author's name: G.W. Bush Current book title is 41: Portrait of My Father. Enter new title for G.W. Bush: Decision Points G.W. Bush title was edited to Decision Points. Command:
Use the function design recipe to develop a function named count_odds. The function takes a list of integers, which may be empty. The function returns the number of odd integers in the list.
Q1: Research Groups In response to popular demand, Dan’s established two research groups A and B composed of his n graduate students. Each of these students is a member of exactly one of the two groups at any given time. The students are numbered from 1 to n in some arbitrary order. To measure the success of his research groups, Dan assigns a citation score to each of them. Initially, both groups have citation score 0. Throughout the semester, events of the following two types happen: Student x publishes a paper in which they cite student y’s work (youcan assume all of the students have been around long enough to have prior research that can be cited). As a result, If x and y are in the same group, their group’s citation score increases by 1. If x and y are in different groups, y’s group’s citation score increases by 5. Dan changes student x’s group (from A to B or from B to A) to have them work on different projects. To assess the overall success of the research groups, Dan…

Exercise: Check Monster Character Exists Description In this series of exercises, you will create functions to create, modify and examine dictionaries that represent characters in an animated film, and the cast members who voice the characters. The keys of the dictionary will be character names. The values in the dictionary will be voice actor names. For this exercise, you will create a function that checks if a character is already in the dictionary. Files monsterfunctions.py : set of functions to work with monster cast dictionaries. Function Name has_character Parameters monsters: a dictionary character: a string, the name of a character Action Checks if character is a key in monsters. Return Value True if character is a key in monsters, otherwise False. Examples monsters = create_monster_cast() monsters = add_cast_member(monsters, "Mike", "William Crystal") has_character(monsters, "Mike") -> True has_character(monsters, "Sully") -> False
Add distribution function in code Requirement 4: DESCENDING ORDER (NOT ASCENDING ORDER) 4. Produce a list of all vaccines and their distributed quantities . 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 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…
In Python a) Create dictionary that stores a single record of information with the attributes (i.e., columns): Name, Age, and School for a student named Jane who is 35 years old and studies at UCLA. b) Write the Python statement that grabs the value of the attribute School from this record. c) Write a Python statement that lists all the attributes of the dictionary. (Use autocompletion to find an appropriate method) d) Write a Python statement that lists all the items (formal word that means the key-value combos). Use autocompletion to find an appropriate method. e) Suppose there was a modification needed for the record and we need to correct the name to be Jane Doe rather than Jane. How would index into the record and assign this new value to the name attribute?

Holiday Travel Vehicle (HTV) sells new recreational vehicles and travel trailers. When new vehicles arrive at HTV, a new vehicle record is created. Included in the new vehicle record are a vehicle serial number, name, model, year, manufacturer, and base cost. When a customer arrives at HTV, he or she works with a salesperson to negotiate a vehicle purchase. When a purchase has been agreed upon, a sales invoice is completed by the salesperson. The invoice summarizes the purchase, including full customer information, information on the trade-in vehicle (if any), the trade-in allowance, and information on the purchased vehicle. The invoice also summarizes the final negotiated price, plus any applicable taxes and license fees. If the customer requests dealer-installed options (simply options), they are listed on the invoice as well. A customer may decide to have no options added to the vehicle or may choose to add many options. Dealer-installed options are described by an option code,…
n this assignment, we will learn a few fundamentals of Data Science. You will read some data values and display some basic statistics of the data set. Your program should: Prompt the user to enter an integer number. Validate the user input to make sure it is an integer. If not, ask the user to enter a valid integer only. You may use the str.isdigit(dataValue) function to check whether the user is entering only digits where dataValue is the user input, and the expression returns True if the entered characters were numbers. Add your integer into a list. Ask the user whether they want to add more data. When the user finishes entering data values, display the count, minimum, maximum, range, and average of your data set. To get the range of the data values, you should subtract the minimum value from its maximum. You can calculate count and average using the appropriate built-in functions.
[Javascript - Question] Create a function that gets the total amount and percentage of covid case data for each Age Group in the covid cases data set(which contains the property "Age Group" in each case array). Age Groups: 'younger than 18', 'between 19 to 28 Years', 'between 29 to 38 Years', 'between 39 to 48 Years', 'between 49 to 58 Years', 'between 59 to 68 Years', 'between 69 to 78 Years', 'between 79 to 88 Years', and 'older than 89' The function getSummaryOfAges(data) should return an Object with the following structure: { 'UnknownAge': { totalAmount: 27, percentageOfTotal: 0.001 }, 'younger than 18': { totalAmount: 39, percentageOfTotal: 0.074 }, 'between 19 to 28 Years': { totalAmount: 68 percentageOfTotal: 0.124 }, 'between 29 to 38 Years': { totalAmount: 59, percentageOfTotal: 0.100 }, ...etc } For the covid case Objects that don't have an Age Group value(meaning it's null). Then these case Objects should be treated as the…
