Python 101 : The "@property" decorator for classes -Setter and Getter methods -

The "@property" refers to a python decorator a function that adds functionalities to another function without modifying its code -.

The "@property" decorator allows us to make a class variable private and define methods to access it, without the need to change any other code that has access to this variable.

For example the code that assigns a value to our variable, does not need to call the setter method, the existing "=" assignment will call the setter without any added code.

Below an example or decorated settergetter and deleter methods:

The "brand" attribute" is protected.

  • __var : private variable - two undescores -, not accessible from outside the class
  • _var : protected variable - one underscore - accessible from within the same package
