Define a class simply so

class Person:

A class variable can be declared as such

    name = "Person"

    age = 0

The constructor for the class

    def __init__(self, name, age):

        self.name = name

        self.age = age

Despite the constructor accepting three arguments, the method gets called only with two arguments
Note that functions that belong to a class are called methods.
A class method can be declared as such

    def hello(self):

        print("Hello", self.name)

A static method can be declared as such

    @staticmethod

    def get_species():

        return "Homo Sapiens"

To create a new instance of the class, simply call

person = Person("John", 30)

To call a method, simply use the dot operator

person.hello()
