What are the benefits of using properties in Python?

Using properties in Python allows for encapsulation, enabling you to control access to attributes and add validation.

Can you give me an example of how to use properties?

Sure! You can use the @property decorator to define a method as a property. For example:

class Circle:
    def __init__(self, radius):
        self._radius = radius

    @property
    def radius(self):
        return self._radius

    @radius.setter
    def radius(self, value):
        if value < 0:
            raise ValueError('Radius cannot be negative')
        self._radius = value

What happens if I try to set a negative radius?

If you try to set a negative radius, it will raise a ValueError due to the validation in the setter method.
