7 PM – Python OOP – Joel

Today we did:

1. We reviewed classes and applied methods.

Homework:

1. 9-1. Restaurant: Make a class called Restaurant. The __init__() method for
   Restaurant should store two attributes: a restaurant_name and a cuisine_type.
   Make a method called describe_restaurant() that prints these two pieces of
   information, and a method called open_restaurant() that prints a message indi
   cating that the restaurant is open.
   Make an instance called restaurant from your class. Print the two attributes individually, and then call both methods.
2. 9-2. Three Restaurants: Start with your class from Exercise 9-1. Create three
   different instances from the class, and call describe_restaurant() for each
   instance.
3. 9-3. Users: Make a class called User. Create two attributes called first_name
   and last_name, and then create several other attributes that are typically stored
   in a user profile. Make a method called describe_user() that prints a summary
   of the user’s information. Make another method called greet_user() that prints
   a personalized greeting to the user.
   Create several instances representing different users, and call both methods
   for each user.
4. 9-4. Number Served: Start with your program from Exercise 9-1 (page 162).
   Add an attribute called number_served with a default value of 0. Create an
   instance called restaurant from this class. Print the number of customers the
   restaurant has served, and then change this value and print it again.
   Add a method called set_number_served() that lets you set the number
   of customers that have been served. Call this method with a new number and
   print the value again.
   Add a method called increment_number_served() that lets you increment
   the number of customers who’ve been served. Call this method with any num
   ber you like that could represent how many customers were served in, say, a
   day of business.
5. 9-5. Login Attempts: Add an attribute called login_attempts to your User
   class from Exercise 9-3 (page 162). Write a method called increment_login
   _attempts() that increments the value of login_attempts by 1. Write another
   method called reset_login_attempts() that resets the value of login_attempts
   to 0.
   Make an instance of the User class and call increment_login_attempts()
   several times. Print the value of login_attempts to make sure it was incremented
   properly, and then call reset_login_attempts(). Print login_attempts again to
   make sure it was reset to 0.
