I'm learning setters and Python 3 coding. I'm not very good at it and have been struggling with this problem for a while now. I need some additional help as my code is not acting the way I want it to. What is the best way to execute the following code?

What I want:

>>>circle = Circle()

>>>circle

Circle(radius=1)

>>>circle.radius_log

[1]

What I am getting:

>>>circle = Circle()

>>>circle

Circle(radius=1)

>>>circle.radius_log

[1, 1]

I do not want the __init__ to reference _radius because it doesn't allow for the ValueErrors to work the way I want them. My code is currently below. What am I missing?

class Circle:

def __init__(self, radius=1):

self.radius_log = [radius]

self.radius = radius

@property

def radius(self):

return s..;@radius.setter

def radius(self, radius):

if(radius < 0):

raise ValueError('Radius cannot be negative!')

self._radius = radius

self.radius_log.append(radius)

@property

def area(self):

return math.pi * self.radius ** 2

@property

def diameter(self):

return self.radius * 2..;@diameter.setter

def diameter(self, diameter):

self.radius = diameter / 2

def __str__(self):

return "Circle of radius" + " " + str(self.radius)

def __repr__(self):

return "Circle(radius=" + str(self.radius) + ")"
