Why am I getting the following error message. Area has been declared as
an attribute of Circle. Thanks, Ray
class Circle:
def __init__(self):
self.radius = 1
def area(self):
return self.radius * self.radius * 3.14159
c = Circle()
c.radius = 3
print c.area()
Traceback (most recent call last):

AttributeError: Circle instance has no attribute 'area'
Probably incorrect indentation. This works:
class Circle:
def __init__(self):
self.radius = 1
def area(self):
return self.radius * self.radius * 3.14159
c = Circle()
c.radius = 3
print c.area()
