__init__()
The __init__()
method initializes a newly created object. It is called each time a new instance of the defined class is created.
Syntax
class ClassName:
__init__(self, param1, param2, ..., paramN):
self.param1 = param1
self.param2 = param2
self.paramN = paramN
self.default_param = value
In a class definition, instance attributes can be set within the __init__()
in two ways:
- With named parameters (
param1, param2, ..., paramN
) that will be required when a class instance is created. - A
default_param
and correspondingvalue
can also be defined so that every instance has access to this parameter.
Additionally, instance attributes can be added to a specific instance variable afterwards:
new_class_instance = ClassName(value1, value2, ..., valueN)
new_class_instance.specific_variable = new_value

The example below showcases the __init__()
method being implicitly called after a new instance of the Home
class, home
, is created with rooms
and stories
attributes passed in:
