Introduction
Welcome to my 60th blog post on the Python journey. On day 60, I learned about Getters and setters method in Python. These methods help us to provide additional functionality to access the values object properties. Let's dive into more details and understand these methods in Python.
So let's get started......
Getters
These methods are used to access the values of an object's properties.
Getters do not take any value.
They are defined using the decorator @property
Getters return the value of a specific property,
Example -
In the below example, MyClass class has a single property, 'value*', which is initialized in the **init method.* The value method is defined as a getter using the @property decorator,** and is used to return the value of the value property.
To use the getter, we can create an instance of the MyClass class, and then access the value property as if it were an attribute:
class MyClass:
def __init__(self, value):
self._value = value
@property
def value(self):
return self._value
obj = MyClass(10)
obj.value
Output
10
Setters
Note that the getters do not take any parameters and we cannot set the value through the getter method.
Hence we make use of the setter method
The setter method can be added by decorating the method with @property_name.setter
Example -
class MyClass:
def __init__(self, value):
self._value = value
@property
def value(self):
return self._value
@value.setter
def value(self, new_value):
self._value = new_value
obj = MyClass(10)
obj.value = 20
More Example -
class MyClass:
def __init__(self, value):
self._value = value
def show(self):
print(f"Value is {self._value}")
@property
def ten_value(self):
return 10* self._value
@ten_value.setter
def ten_value(self, new_value):
self._value = new_value/10
obj = MyClass(10)
obj.ten_value = 67
print(obj.ten_value)
obj.show()
Output -
67.0
Value is 6.7
Note -
Getters provide a convenient way to access the values of an object's properties while keeping the internal representation of the property hidden.
Getter and setter methods can be useful for encapsulation and data validation.
