In this lab, we will practice defining classes with custom __init__ methods. We will define two classes, Driver and Passenger in the cells below. Follow the instructions in order to get the tests to pass.

You will be able to:

• Define custom __init__ methods for object initialization
• Create instance variables in the __init__ method
• Use default arguments in the __init__ method

Let's start off by defining Driver and Passenger classes. In the Passenger class, we will want our passengers to have the attributes first, last, email, and rides_taken for their first name, last name, email, and number of rides they have taken. Let's provide our __init__ method with the default argument of 0 for the rides_taken attribute since new passengers should not have taken any rides.

After we've defined our Passenger __init__ method, check it out by initializing a new passenger with the first name "Rebecca", the last name "Black", and the email "[email protected]". Don't worry about creating instance methods or using any attribute decorators in this lesson. We can just instantiate instance variables and use those to access the instance's attributes.

# Define Passenger Class Here

rebecca_black = None # initialize Rebecca Black here
print(rebecca_black.first) # "Rebecca"
print(rebecca_black.last) # "Black"
print(rebecca_black.email) # "[email protected]"
print(rebecca_black.rides_taken) # 0

Great work! Rebecca Black is now in the system and ready to request her ride to the party on Friday! Friday! Friday!

In the Driver class, define an __init__ method that initializes a driver with the attributes first, last, and favorite_hobby for their first name, last name, and favorite hobby. Let's provide a default argument of "driving" for favorite_hobby, since we would hope they are doing what they love!

After we have our Driver __init__ method, let's initialize a driver with the first name "Dale", last name "Earnhardt". Again, don't worry about creating any instance methods or using any property decorators.

# Define Passenger Class Here

dale_earnhardt = None # initialize Dale Earnhardt here
print(dale_earnhardt.first) # "Dale"
print(dale_earnhardt.last) # "Earnhardt"
print(dale_earnhardt.favorite_hobby) # "driving"

Awesome, maybe Dale will be Rebecca's driver to the party on Friday! Friday! Friday!

In this lab, we practiced definining custom __init__ methods that allowed us to initialize new instances with a set of predetermined attributes and default attributes.
