How do you define a class in python

Here's a simple example of a class:class Animal: def init(self, name, noise): self.name = name self.noise = noise def make_noise(self): print(self.noise) here init is the "initializer" (or sometimes called the "constructor") of the class. This gets run when a new instance of the class is created. make_noise is one of the class's methods, which prints the noise the animal makes. You use this method on an instance of the class. Python passes the instance of the class being called as the first argument to any of the functions in the class, this is what we're calling "self". So in the following example:dog = Animal("dog", "bark") dog.make_noise() dog, "dog" and "bark" are used as the self, name and noise parameters in init, and dog is passed as the self parameter in make_noise. So this program would output "bark".
