python language Write a function that overwrite the greater than method for a class. The class has a field variable called score. The lower the score, the better. INPUT: Nothing? NOTE: this method is inside the class OUTPUT: Nothing is output RETURNED: The boolean result of the new comparison
True or False A static method can reference an instance variable.
True or False The versions of an overloaded method are distinguished by the number, type, and order of their parameters.
Add a toString() method to Fraction class that returns the fraction as aString in the form "x / y", where x and y are numerator and denominatorrespectively. As the method does not do any display itself, the output can be done by a client program that calls the method in an output statement. Use client program to test this functionality; i.e. provide an output statement to display a fraction as its String representation. class Fraction2{private int n, d;public Fraction(){this.n = this.d = 0; //Initialize the values}public Fraction(int n, int d){this.n = n; //Initialize the variablesthis.d = d;}//Define the getter function getNum() that returns the numeratorpublic int getNum(){//Returns numeratorreturn n;} //Define the getter function getDen() that returns the denominatorpublic int getDen(){//Returns denominatorreturn d;}//Define the boolean function isZero() that returns 0 if numerator is 0 and denominator is not equals to zeropublic boolean isZero(){return(getNum() == 0 &&…
Write in python and please include docstring. Write a class named Employee that has private data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address. Write a separate function (not part of the Employee class) named make_employee_dict that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary. For example, it…
Add three methods to the Student class that compare twoStudent objects. One method (__eq__) should test for equality. A second method (__lt__) should test for less than. The third method (__ge__) should test for greater than or equal to. In each case, the method returns the result of the comparison of the two students’ names. Include a main function that tests all of the comparison operators. Note: The program should output in the following format: False: False True: True True: True False: False True: True True: True True: True True: True True: True True: True

It returns a Boolean value based on the following criteria. An aircraftrequires maintenance on the following schedule: Last maintenance date is 3 months or more Last maintenance mileage is 150,000 air miles or moreo shouldRetire()- this method should return a Boolean value that determines whether anaircraft is ready to be retired from service, based on the following criteria: More than 20 years past date put into service More than 2,000,000 air mileso toString()- See sample run for toString formato Only the getters and setters that are actually used.

In C#, how would you write (2) programmer defined methods as described below: Method #1 (GreetingGeneric) — a type void programmer defined method does not require any parameters. It should output a generic greeting line for a letter. For example: "Dear Customer", "Dear Student", etc. Method #2 (GradeMessage) — a type void programmer defined method that has (3) parameters; (string, string, double) for (name, assignment, and grade) and should output the passed parameters in sentence format: GradeMessage("Jimmy", "Midterm Exam", 79.5) would output: Jimmy took the Midterm Exam and got 79.5 points. The Main() method for this program should: call Method #1 to output the generic greeting ask the user to enter a name, assignment, and grade and pass them to Method #2 for output. Input should only be done in the Main() method and output in the programmer-defined methods.
