In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie...

Please do in Java In many computer systems and networks,different users are granted different levels of access to different resources. In this case, you are given a int[] rights, indicating the privilege level of each user to use some system resource. You are also given a int minPermission, which is the minimum permission a user must have to use this resource. You are to return a String indicating which users can and cannot access this resource. Each character in the return value corresponds to the element of users with the same index. 'A' indicates the user is allowed access, while 'D' indicates the user is denied access. Constraints users will contain between 0 and 50 elements, inclusive. Each element of users will be between 0 and 100, inclusive. minPermission will be between 0 and 100, inclusive. Examples a) {0,1,2,3,4,5} 2 Returns: "DDAAAA" Here, the first two users don't have sufficient privileges, but the remainder do. b) {5,3,2,10,0} 20 Returns: "DDDDD"...

create a class in python with a constructor To create instances of the user defined class and practice applying them. Practice implementing loops. Part 1 Instructions:Create a class called BankAccount with the following variables: balancenameaccount_id Create 1 constructor for the class BankAccount (with or without parameters, your choice, but only 1): def __init_(self, name, account_id, balance)def __init_(self) Create the following methods in the BankAccount class: def viewAccountInfo() //prints all account information def withdraw(self, amount) //withdraws from the balance def deposit(self, amount) //deposits to the balance Your task after your class has been created: Create two objects, "personal" and "joint_account"with initial balances of:personal = 1000ドルjoint_account = 3000ドルUse the constructor to create the objects. Create a program that prompts the user which account they would like to access personal or jointWhich account would you like to access? 1. Personal2. Joint...

In Python code: Using this website: https://en.wikipedia.org/wiki/Greenhouse_gasCreate a named tuple to contain each Gas Concentration data for these columns: Gas,Pre-1750,Recent,Absolute increase since 1750,Percentage increase since 1750. Design a class to hold this named tuple and add necessary dunders to support initialization, string conversion, sorting by a specific column (like 'Recent' for example) and searching.

For beginning Java, need help with this: " Purpose: Define class using OO approach Understand how to create and manipulate list of objects Design and create a well-structure program using basic programming constructs and classes Description: Write a program to help you to manage courses you are taking this semester. Your program provides the following options: List all courses Add a course Search word: show all the courses that has the word in the course title (ask the user for the word) List >= input-unit: show all the courses that has unit >= input-unit (ask the user for input) Exit Explanation of options: The program prints your course list. Initially, it should say "Your list is empty" The program asks the user input for a course including: course ID, number of units and title. The program asks the user to input the search word. Then, display all courses that has that word in the title. The search must be case-insensitive. For example, "computer" and...
