- The @property built-in decorator is used to create the properties on any method in the class.
- @property is used to declare the method as a property.
- @property-name.setter is used for the setter method which sets the value to a property
- @property-name.deleter is used for the delete method which deletes a property.
class Courses: def __init__(self, courseName): self.__courseName = courseName #private instance variable @property # Declaring the method as Property def courseName(self): return self.__courseName @courseName.setter #Property Setter which sets the value to a property def courseName(self,updatedValue): self.__courseName = updatedValue @courseName.deleter def courseName(self): del self.__courseName
- Above, @property decorator applied to the courseName() method. The courseName() method returns the private instance attribute value __courseName.
- To modify the property value, we have defined the setter method for the courseName property using @property-name.setter decorator. The setter method takes the updatedValue argument that is used to assign the private attribute value.
- Use the @property-name.deleter decorator for the method that deletes a property. The deleter would be automatically called when you delete the property using keyword del.
