Use methods to access and mutate the attribute.Access and mutate the attribute directly.Typically, you’ll have at least two ways to access and mutate attributes. In many cases, you’ll need to access and mutate this state, which involves accessing and mutating the attributes. These attributes are just variables that you can access through the instance, the class, or both.Īttributes hold the internal state of objects. When you define a class in object-oriented programming (OOP), you’ll likely end up with some instance and class attributes. Getting to Know Getter and Setter Methods Source Code: Click here to get the free source code that shows you how and when to use getters, setters, and properties in Python. It’ll also be a plus if you have basic knowledge of Python properties and descriptors. To get the most out of this tutorial, you should be familiar with Python object-oriented programming. Decide when setter and getter methods can be the right tool for the job.Explore other tools to replace getter and setter methods in Python.Replace getter and setter methods with properties.Write getter and setter methods in your classes.Because of this, you’ll find some situations where getters and setters are preferable over properties. In Python, you’ll typically expose attributes as part of your public API and use properties when you need attributes with functional behavior.Įven though properties are the Pythonic way to go, they can have some practical drawbacks. These methods allow you to access and mutate private attributes while maintaining encapsulation. If you come from a language like Java or C++, then you’re probably used to writing getter and setter methods for every attribute in your classes.
