Classes ======= In Python, a class is a blueprint for creating objects. It defines a set of attributes and methods that the objects of the class will have. Here's an example of a simple class: .. code-block:: python class Person: def __init__(self, name, age): self.name = name self.age = age def say_hello(self): print(f"Hello, my name is {self.name} and I am {self.age} years old.") This class defines a ``Person`` object with a ``name`` and an ``age`` attribute, and a ``say_hello()`` method that prints a greeting. You can create an instance of a class by calling the class as if it were a function, passing in any required arguments. Here's an example: .. code-block:: python person1 = Person("Alice", 25) This creates a ``Person`` object named ``person1`` with a ``name`` of ``"Alice"`` and an ``age`` of ``25``. You can access the attributes of an object using the dot notation. Here's an example: .. code-block:: python print(person1.name) This will output ``"Alice"``. You can call the methods of an object using the dot notation as well. Here's an example: .. code-block:: python person1.say_hello() This will output ``"Hello, my name is Alice and I am 25 years old."``. I hope this helps! Let me know if you have any other questions. TODO: elaborate on classes and demonstrate building all of the buildings inside the castle walls with this code: .. literalinclude :: ../../../src/demo/house.py :language: python Note that this code can now build a complete castle from previous steps. .. literalinclude :: ../../../src/demo/village.py :language: python
