sure! the `property` function and `@property` decorator in python allow you to define properties on a class that act like attributes but have custom getter, setter, and deleter methods. this is useful for controlling access to attributes and adding validation or computation logic.
here's a tutorial on how to use the `property` function and `@property` decorator in python 3:
1. using the `property` function:
you can use the `property` function to create a property on a class. the `property` function takes up to four arguments: a getter function, a setter function, a deleter function, and a docstring.
here's an example demonstrating the use of the `property` function:
2. using the `@property` decorator:
you can also use the `@property` decorator to define properties in python. the `@property` decorator makes it easier to define properties without explicitly using the `property` function.
here's an example demonstrating the use of the `@property` decorator:
in both examples, we defined a `circle` class with a `radius` property that has custom getter, setter, and deleter methods. the property allows us to get, set, and delete the radius of the circle while enforcing some validation logic.
i hope this tutorial helps you understand how to use the `property` function and `@property` decorator in python 3! let me know if you have any questions.
