- In Python: Write a class named Pet, which should have the following data attributes: _ _name (for the name of a pet) _ _animal_type (for the type of animal that a pet is. Example values are 'Dog','Cat', and 'Bird') _ _age (for the pets age) The Pet class should have an _ _init_ _ method that creates these attributes. It should also have the following methods: set_nameThis method assigns a value to the _ _name field set_animal_typeThis method assigns a value to the _ _animal_type field set_ageThis method assignsa value to the _ _age field get_nameThis method assignsa value to the _ _name field get_animal_typeThis method assignsa value to the _ _animal_type field get_ageThis method assignsa value to the _ _age field Once you have written the class, write a program that creates an object of the class and prompts the user to enter the name, type and age of his or her pet. This data should be stored as the objects attributes. Use the objects accessor methods to retrieve the pets…Design a class named CustomerRecord that holds a customer number, name, and address. Include separate methods to 'set' the value for each data field using the parameter being passed. Include separate methods to 'get' the value for each data field, i.e. "return" the field's value. Pseudocode:Mick’s Wicks makes candles in various sizes. Create a class for the business named Candle that contains the following data fields: color - of type String height - of type int price - of type double Create get methods for all three fields. Create set methods for color and height, but not for price. Instead, when height is set, determine the price as $2 per inch. Create a child class named ScentedCandle that contains an additional data field named scent (of type String) and methods to get and set it. In the child class, override the parent’s setHeight() method to set the price of a ScentedCandle object at $3 per inch.
- Part 3. arange Method Define a method in simpy named arange. Its purpose is to fill in the values attribute with range of values, like the range built-in function, but in terms of floats. It has three parameters in addition to self, the last being optional: 1. start - a float indicating the first value in the range 2. stop - a float that is not included in the produced range values 3. step - a float whose default value is 1.0 that indicates how to increase (or decrease) each subsequent item in the generated range. Unlike the built- in range function, this can be a fractional, float value. Step cannot be 0.0. Think carefully about what the value of step tells you about how to design your loop(s) for this method. Before any looping, you should assert step != 0.0 to be sure you avoid an infinite loop with an invalid argument. positive = Simpy([]) positive.arange(1.0, 5.0) print("Actual: ", positive, " - Expected: Simpy([1.0, 2.0, 3.0, 4.0])") fractional = Simpy([]) positive.arange (0.0,…mau Open Leathing inta... - The class has data members that can hold the name of your cube, length of one of the sides and the color of your cube. - The class has a constructor that accepts the name, length of one of the sides, and color as arguments and sets the data members to those values. - The class has the following methods to set the corresponding data member. setName(string newName) setSide(double newSide) setColor(string newColor) - The class has a method called getVolume() that returns the volume of the cube, calculated by cubing the length of the side. - The class has a method called volumelncrease(double newVolume) that receive the percent the volume should increase, and then the side to the corresponding value. i - For example, 2.5 indicates 2.5% increasing of the volume. So you take the current volume, increase it by 2.5%, and then find the cube root to calculate the new side length. You can use the built in function called cbrt, part of the math library, to find the cube…Static & Not Final Field: Accessed by every object, Changing Non-Static & Final Field: Accessed by object itself, Non-Changing Static & Final: Accessed by every object, Non-Changing Non-Static & Not Final Field: Accessed by object itself, ChangingRead the following situation and decide how the variables should be defined.

- Design a class named Stocks that contains: Private Data Members: A string data field named symbol for the stock’s symbol. A string data field named name for the stock’s name. A double data field and prevClosingPrice that stores the stock price for the previous day. A double data field named currentPrice that stores the stock price for the current day. Accessor and mutator functions for all data members. A method named getChangePercent( ) that returns the percentage changed from the previous closing price to the current price. The percentage is calculated by subtracting the previous closing price from the current price then, dividing by the current price. A method named nextDayPrice( ) that returns the predicted stock price for the next day assuming that the change percentage remains the same. Implement the class.

Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.
- At most, a class can contain ____________ method(S). 0 1 2 any number ofWrite a program named DemoJobs for Harolds Home Services. The program should instantiate several Job objects and demonstrate their methods. The Job class contains four data fields—description (for example, wash windows), time in hours to complete (for example, 3.5), per-hour rate charged (for example, $25.00), and total fee (hourly rate times hours). Include properties to get and set each field except the total fee—that field will be read-only, and its value is calculated each time either the hourly fee or the number of hours is set. Overload the + operator so that two Jobs can be added. The sum of two Jobs is a new Job containing the descriptions of both original Jobs (joined by and), the sum of the time in hours for the original Jobs, and the average of the hourly rate for the original Jobs. Harold has realized that his method for computing the fee for combined jobs is not fair. For example, consider the following: His fee for painting a house is $100 per hour. If a job takes 10 hours, he earns $1000. His fee for dog walking is $10 per hour. If a job takes 1 hour, he earns $10. If he combines the two jobs and works a total of 11 hours, he earns only the average rate of $55 per hour, or $605. Devise an improved, weighted method for calculating Harolds fees for combined Jobs and include it in the overloaded operator+() method. Write a program named DemoJobs2 that demonstrates all the methods in the class work correctly.Write a class named Car that has the following data attributes: __year_model: (for the car's year model)__make: (for the make of the car)__speed: (for the car's current speed) In addition, the class should have the following methods: __init__ method that accepts the car’s year model and makes arguments. These values should be assigned to the object’s __year_model and __make data attributes. It should also assign 0 to the __speed data attribute.accelerate: The accelerate method should add 5 to the speed data attribute when it is called.brake: The brake method should subtract 5 from the speed data attribute each time it is called.get_speed: The get_speed method should return the current speed Next, design a program that creates a Car object and then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method five times. After each call to the brake method, get the current speed of the car…
