## Module Creation: `contacts`### Step-by-Step Instructions1. **Create a Python File** - Name the file: `contacts.py`.2. **Define a Class** - Class Name: `Contacts`.3. **Initialize the Class (`__init__` function)** - **Parameters**: - `self`: standard positional parameter. - `filename`: a keyword parameter. - **Process**: - Store `filename` as a member variable. - Create an empty dictionary as another member variable. - Open the filename and load JSON contents into the dictionary. - Handle `FileNotFoundError` gracefully if the file does not exist.4. **Define a Member Function: `add_contact`** - **Parameters**: - `self`: standard positional parameter. - `id`: keyword parameter. - `first_name`: keyword parameter. - `last_name`: keyword parameter. - **Process**: - Check if `id` exists in the dictionary; if yes, return the string "error". - If not, add `id` with `[first_name, last_name]` as a key-value pair. - Sort the dictionary by `last_name` and then by `first_name`, ignoring case. - Write the updated dictionary back to the file. - Return the key-value pair that was added.

Complete the following sentence. If more than one function is present in a file, the top function is a normal or function, while the ones below it are called local functions.
createDatabaseOfProfiles(String filename) This method creates and populates the database array with the profiles from the input file (profile.txt) filename parameter. Each profile includes a persons' name and two DNA sequences. 1. Reads the number of profiles from the input file AND create the database array to hold that number profiles. 2. Reads the profiles from the input file. 3. For each person in the file 1. creates a Profile object with the information from file (see input file format below). 2. insert the newly created profile into the next position in the database array (instance variable).
5. In lab12_p5.py a function read_data_file has been created. This function takes in one string parameter that represents the name of the file to be processed. This function reads data from the provided file and returns a dictionary representation of the data stored in this file.

This part of the quiz will contain 4 parts. A function called grade, a function called pgrade, a prototype file called grade.h and a main function. In this part you will create the main function which will do the following: main This main function will use the functions grade and pgrade to produce the grades for the following students and display the appropriate grade with the appropriate message. The semester grade will be based on the fact that the quiz average is 25% of the grade, the final is 20% of the grade, assignments is 20% of the grade and programs are 35% of the grade. The student grades are as follows: Student Name Assignments Programs Quiz Ave Final Tom 63 Francis Maria Jan 75 90 95 85 sample of output Harry Grade B Good 85 75 95 90 93 92 71 69 87 91 73 A
Milestone #1 - Ask Quiz Type In a file called main.py, implement a program that asks the user for a quiz type and prints the file name for that quiz type. The program should have one input prompt: the integer value of the personality quiz number. Your program should print the welcome message and the list of the personality quizzes, ask for the test number, and then print the file name. You are required to use the provided dictionary with the personality quizzes names. The list of the personality quizzes should be printed in alphabetical order. See example below. Welcome to the Personality Quiz! What type of Personality Quiz do you want to run? 1 BabyAnimals 2 Brooklyn99 3 Disney 4 Hogwarts 5 MyersBriggs 6 Sesame Street 7 - StarWars 8 - Vegetables

You are implementing a simple file system for an operating system for managing files and folders; similar to Windows or UNIX. Your design should follow the following guidelines i) The entire file system is represented by an object which is the reference to the root folder ii) Any folder in the file system may contain two types of items, folders (subfolder) and files and you want to treat both in the same way iii) possible operations: getName, getPermission, listItem What is the most appropriate design pattern?
