python property without setter

in python, the property decorator allows you to define getter, setter, and deleter methods for a class attribute. however, there are scenarios where you might want to create a read-only property without a setter. this tutorial will guide you through the process of creating a python property without a setter, providing a clear understanding and practical examples.
properties in python are a way to control the access, modification, and deletion of attributes in a class. the property decorator is used to define these special methods. a basic property structure includes a getter, setter, and deleter. however, if you don't want to allow the modification of an attribute, you can omit the setter.
to create a property without a setter, you only need to define the getter method. this way, the attribute becomes read-only, and any attempt to set its value will raise an attributeerror.
let's use a practical example to illustrate the use of a read-only property without a setter. consider a class representing a circle with a radius. we want to provide a read-only property for the circumference without allowing users to change the radius.
in this example, the radius property is read-only, and attempting to set a new value will raise an attributeerror. the circumference property, which depends on the radius, can be accessed without any issues.
creating a python property without a setter allows you to define read-only attributes in your classes. this can be particularly useful when you want to expose certain values but prevent them from being modified externally. use this tutorial as a reference when designing classes with properties tailored to your specific needs.
