Python Class Properties

This lesson is part of Python · All levels

Summary

Properties are a special way of accessing attributes as if they were a normal variable, when behind the scenes there is code running. The @property decorator changes the method into a read attribute, while the @nama.setter adds logic when the value is written. This pattern keeps the data protected while keeping the class interface simple.

Key points

@property makes methods call without a curve like a normal attribute.
@x.setter defines logic when values are changed; @x.deleter to delete.
The property is useful for validating data, derivative values, and hiding internal storage.
Variables prefixed with one underscore _name denote internal attributes according to convention.
