Question

Transcribed Image Text:23.5 LAB: Random values
In main.py define the RandomNumbers class, which has three integer attributes: var1, var2, and var3. Write getter method for each attribute:
get_var1), getvar2() and get var3(. Then write the following 2 instance methods:
• set_random_values()- accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers within
the range of the low and high input values (inclusive).
• get_random_values() - prints out the 3 random numbers in the format: "Random values: var1 var2 var3"
Ex: If the input is:
15
20
the output may be:
Random values: 17 15 19
where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive).

- g) Make a class Class (as in a class of students, not a class as in a class of objects) that stores several Student objects. Store a list of students in an attribute called students. The initializer method should initialize the class as an empty class (no students). Implement a method add_student() that takes an object of class Student and adds it to class. Implement method pass_rate() that determines the fraction of students that pass the class (have a grade of >= 6). python code!!arrow_forward• RectangleTest class: o Perform the following actions in the main method: • Create an object named r1 of the Rectangle class using the default constructor. • Using the set methods, initialize rl to have width 3.0 and length 5.2. • Use the printDimensions method to output all the data (width & length) related to r1. • Create another object named r2 of the Rectangle class with width 2.6 and length 5.4 using the overloaded constructor. • Print out r2 (width & length) using the get methods. • Print out the area and the perimeter of r1 using the calculateArea and calculatePerimeter methods. • Print out the area and the perimeter of r2 using the calculateArea and calculatePerimeter methods.arrow_forward/*** This class describes a tweet.
