Need help python questions: 1) Why is using "while True" not a good idea? Is there any situation in that we have to use it? 2) Why do we use " _" before the name of a variable? 3) What are Dunder/Magic Methods in Python? Explain with an example. 4) What is the "self" in your code? Why do we use it in a method's header?

Please include doctring, write only in python, and utilize the example code so I understand this program: 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…
c++ I have to find the Horner method and the other method, the value is supposed to be 15, and I had to check the time it took to run the program I believe, or something like that. I'd really appreciate your help. thanks so so much.
i just want to know true or false dont write complicated process. please quickly , thanks ! 4.A declaration of public method in a class means that "outside" methods can't call it --only methods within the same class can.
How to does this look like in python and do you know how to write get methods? so write those 3 get methods inside AssignmentResult AssignmentResult -needs get_assignment(), get_id(), get_grade() Assignment -_str_ is returning wrong -needs get_name() and get_difficulty() Student -needs arguments get_id(self) -> int: """ Returns the ID of the student as specified in the constructor. :return: The student's ID """ get_grade(self) -> float: """ Returns the grade as specified in the constructor. :return: The grade the student received for this assignment """ get_assignment(self) -> Assignment: """ Returns the assignment as specified in the constructor. :return: The assignment that the student worked on to create this result """
I am not sure how to do this problem recursively DO NOT use System.exit(). DO NOT add project or package statements. DO NOT change the class name. DO NOT change the headers of ANY of the given methods. DO NOT add any new class fields (instance variables). ONLY display the result as specified by the example for each problem. DO NOT print other messages, follow the examples for each problem. You may USE the StdOut library. On RecursiveAppend.java write a recursive method appendNTimes that receives two arguments, a string and an integer. The method appendNTimes returns the original string appended to the original string n times. Use the following method header:public static String appendNTimes (String original, int n) Examples: appendNTimes("cat", 0) returns “cat” appendNTimes("cat", 1) returns “catcat” appendNTimes("cat", 2) returns “catcatcat” The following restrictions apply to method appendNTimes: the CODE MUST BE RECURSIVE Do not use loops (while, do/while, or for).…
Help me solve this problem Multiple Choice & Some Date FashionWhen writing methods, always write the method skeleton first and make sure it compiles.1. Write a header with an appropriate return type and parameters.2. Write the body with curly braces.3. Declare a variable that matches the return type and initialize it with a placeholder value.4. Return that variable.With practice, these mechanical steps will become second-nature and will not require any problem solving on your part.Practice these steps and then solve the DateFashion problem using sequential if statements along with the return statement. The idea is to get more practice with multi-branch logic. Therefore, don't use any of the binary Boolean operators like && or ||. You may use the Boolean not operator (!). https://codecheck.it/files/1810031754ckr22amvk7fr6jtdrtqgrmqle
Can you help me if this my program use method or class. Because my teacher what us to use method or class, not all program are in main method. Can you correct it if i dont use the main or class. I am firstimer in programming. Thanks.
Correct the following wrong statements. In Java, once a variable is declared in a method as local variable, it will be visible and could be used in any other method in the program.
