python class takes no arguments

Показать описание

in python, you can create classes that take no arguments by defining a special method called __init__. in this tutorial, we will learn how to create a python class that takes no arguments and explore its usage with a code example.
to create a python class that takes no arguments, you need to define the class and its methods. you can use the class keyword to define the class and the def keyword to define its methods. however, in this case, you won't define an __init__ method that takes any arguments.
here's a basic example of a class called noargumentclass that takes no arguments:
in the code above, we've defined a class called noargumentclass with two methods, say_hello and say_goodbye. the __init__ method takes only one argument, self, which is a reference to the instance of the class. however, it doesn't take any other arguments.
even though the __init__ method doesn't take any arguments, you can still initialize class attributes within it. class attributes are shared among all instances of the class. to initialize class attributes, you can use the self keyword within the __init__ method.
here's an example of initializing a class attribute in the noargumentclass:
in this updated code, we've added a message attribute to the class, and it gets initialized when an instance of noargumentclass is created.
now that we've defined our class, let's see how we can use it:
when you run the code above, it will create an instance of noargumentclass, call its methods, and access its class attribute. you should see the following output:
congratulations! you have successfully created a python class that takes no arguments and learned how to initialize class attributes and use the class methods. this can be useful when you want to create classes that don't require any specific initialization data but provide functionality through methods and attributes.
