A developer is implementing a class to represent a car. The __init__ method should set the make and model as instance attributes. Which code snippet correctly binds these attributes to the instance?

class Car: def __init__(self, make, model): Car.make = make; Car.model = model

class Car: def __init__(self, make, model): self.make = make; self.model = model

class Car: def __init__(self, make, model): make = make; model = model

class Car: def __init__(make, model): self.make = make; self.model = model

A developer defines a class called Logger with no __init__ method. They then attempt to create an instance with logger = Logger('debug'). What happens?

A syntax error occurs because the class has no __init__.

The instance is created, and the argument is ignored.

A TypeError is raised because the default constructor takes no arguments.

The instance is created, and it gets a level attribute set to 'debug'.

A developer needs to define a class named Book where each book object must have a title and an author, both provided at the time of creation. Which constructor declaration is correct?

def __init__(self): self.title = 'Unknown'; self.author = 'Unknown'

def __init__(self, author, title): self.title = title; self.author = author

def __init__(self, title, author): self.title = title; self.author = author

def __init__(title, author): self.title = title; self.author = author

A logistics company needs a `Shipment` class where each shipment object is created with a tracking number and a destination city. The tracking number must be stored as an instance attribute. Which class definition correctly initializes these attributes when a shipment is created with `Shipment('TRK123', 'Berlin')`?

class Shipment: def __init__(self, tracking, city): self.tracking = tracking self.city = city

class Shipment: def __init__(self, tracking): self.tracking = tracking self.city = 'Unknown'

class Shipment: def __init__(tracking, city): self.tracking = tracking self.city = city

class Shipment: def __init__(self, tracking, city): tracking = tracking city = city

A configuration class `AppConfig` is designed to be initialized with a `host` and a `port`. The constructor is `def __init__(self, host, port=8080):`. Which call correctly creates a config with host `'localhost'` and port `9090`?

config = AppConfig('localhost', 9090)

config = AppConfig(port=9090, host='localhost')

config = AppConfig('localhost')

config = AppConfig(9090, 'localhost')
