That is, .__init__() initializes each new instance of the class. You can give .__init__() any number of parameters, but the first parameter will always be a variable called self. When you create a new class instance, then Python automatically passes the instance to the self parameter...

Note that besides the __main__ function, you also have an __init__ function that initializes an instance of a class or an object. Simply stated, it acts as a constructor or initializer and is automatically called when you create a new instance of a class. With that function, the newly...
