What are constructor parameters in Python?

What are constructor parameters in Python?

Constructor parameters in Python are variables that you pass to a class when creating an instance. They allow you to initialize the object's attributes.

Can you give me an example of a class with constructor parameters?

Sure! Here's a simple example:

class Dog:
    def __init__(self, name, age):
        self.name = name
        self.age = age

my_dog = Dog('Buddy', 3)

What happens if I don't provide the parameters?

If you don't provide the required parameters, Python will raise a TypeError indicating that the required positional arguments are missing.

Can constructor parameters have default values?

Yes, you can set default values for constructor parameters. For example:

def __init__(self, name='Unknown', age=0):
    self.name = name
    self.age = age
