Python Encapsulation

This lesson is part of Python · All levels

Summary

Encapsulation combines data and methods in a class while limiting direct access to internal details. Python has no private modifier like other languages, but rather through a name convention: one _x underscore for internal and two __x underscore that triggers name mangling. Getters, setters, or properties are then used to control access to the data.

Key points

Encapsulation = packing data and methods into a class and restricting direct access to internal attributes.
The name is a protected convention: accessible, but not recommended from outside.
The name triggers the name mangling to be a class name so it's hard to access from the outside.
Provide an official method of reading and changing data in the form of a getter, setter, or property.
