Step $4.$ Create new module named order.py

$1.$ Import the Person Class into the order.py module

Before you start writing the Order class, you$$ll need to import the Person class from another

file or module where it is defined. This is necessary because we will use a Person object as

the owner of the order

import person

$2.$ Define the Order Class and a Class Variable

$$ Create a class named Order.

$$ Inside the class, define a class variable order$\_$count and set it to $0.$ This variable will

track the total number of orders created.

$3.$ Define the Constructor $(\_\_$init$\_\_$ Method$)$

$$ Inside the class, define the $\_\_$init$\_\_$ method. This is the constructor, which gets called

automatically whenever a new Order object is created.

$$ The constructor should accept three parameters:

$$ price: the price of the order.

$$ name: the name of the order.

$$ owner: a Person object that represents the owner of the order.

$$ Inside the constructor:

$$ Increment the order$\_$count class variable by $1$ each time a new order is created.

$$ Store the price and name as private instance variables $($use double underscores like

$\_\_$price and $\_\_$name$).$

$$ Store the owner as an instance variable $\_$owner $($it doesn$$t need to be private but

should be managed carefully$).$

$4.$ Write Getter and Setter Methods for price

$$ Write a get$\_$price$()$ method that returns the value of $\_\_$price.

$$ Write a set$\_$price$($price$)$ method that updates the value of $\_\_$price.

$5.$ Write Getter and Setter Methods for name

$$ Write a get$\_$name$()$ method that returns the value of $\_\_$name.

$$ Write a set$\_$name$($name$)$ method that updates the value of $\_\_$name.

$6.$ Write the displayInfo$()$ Method

$$ Write a method called displayInfo$()$ to display information about the order.

$$ Inside this method:

$$ Print a separator line to make the output clearer.

$$ Print the name and price of the order.

$$ Call the displayInfo$()$ method of the owner $($the Person object$)$ to display the person$$s

information. You can use self.$\_$owner.displayInfo$()$ to access the person$$s info.

Output should look like this:

$========================================$

DisplayInfo Order

$========================================$

Name: Coffee

Name: $19\mathrm{.}99$

$----------------------------------------$

name: Albert Einstein money: $ $100\mathrm{.}00$

$7.$ Define the main$()$ Function

$$ Write a main$()$ function that will be executed when the program runs.

$$ Inside the main$()$ function:

$$ Create a Person object $($using the Person class from the person module$).$ You will use

this person as the owner of the order.

$$ Create an Order object, passing the price, name, and the Person object $($owner$)$ to the

constructor.

$$ Call the displayInfo$()$ method of the Order object to display the order and owner details.

$8.$ Ensure the Program Runs Correctly

At the bottom of your file, add the standard Python entry point:

if $\_\_$name$\_\_=="\_\_$main$\_\_"$:

main$()$
