Whats wrong here

Question

I'm getting an error saying that the class circle has no attribute called radius here's my code

class Circle:
# create a class called circle
    def __init__(self, diameter):
        # creates an init that takes self and diameter
        self.diameter = diameter
        # When run this will cause whatever value put in for diameter to be the diameter
        @property
        # Whatever method put here will be a property of the circle class
        def radius(self):
            self.radius = radius
        # define a new method called self
            return self.diameter / 2
        # this will return the diameter divided by to (or the radius)
small = Circle(10)
print(f"The diameter of the circle is {small.diameter}")
print(f"The radius of the circle is {small.radius}")

Hi Aizah

I tested your code and modified it a bit, now it works:

class Circle:
# create a class called circle
    def __init__(self, diameter):
        # creates an init that takes self and diameter
        self.diameter = diameter
        # When run this will cause whatever value put in for diameter to be the diameter
    @property
    # Whatever method put here will be a property of the circle class
    def radius(self):
    # define a new method called self
        return self.diameter / 2
    # this will return the diameter divided by to (or the radius)
small = Circle(10)
print(f"The diameter of the circle is {small.diameter}")
print(f"The radius of the circle is {small.radius}")

I did the following:

indented the radius method correctly
deleted this line self.radius = radius

This is the output I got:

The diameter of the circle is 10
The radius of the circle is 5.0

You can test it out yourself!
