AttributeError: 'area' object has no attribute 'areaofcircle' - shane1236 - Aug-01-2019
Hello everyone,
I'm facing trouble in the following code, can somebody help me.I am new here even I don't know how to post my code sorry about that. One more thing I want to
understand in the first for loop I passed values to the class, but the variables are taking random value, why we are passing these values, kindly let me know
import math, random
class area():
def __init__(self,radius=None, length=None, breath=None, height=None, base=None):
if radius==0 and breath!=0:
self.radius=random.uniform(1.1, 9.5)
self.length=random.uniform(10.5,15.5)
self.breath=random.uniform(15,20)
self.height=random.uniform(20,25)
self.base=random.uniform(26,32)
elif length==0 and heigh!=0:
self.radius=random.uniform(1.1, 9.5)
self.length=length
self.breath=random.uniform(15,20)
self.height=height
self.base=base
elif height==0 and base!=0:
self.radius=radius
self.length=random.uniform(1.1, 9.5)
self.breath=breath
self.height=random.uniform(1.1, 9.5)
self.base=base
def areaofcircle(self):
return (self.radius**2)*math.pi
def areaoftriangl(self):
return 0.5*(self.height)*(self.base)
def areaofrectangle(self):
return (self.length)*(self.breath)
areas=[]
for i in range(0,10):
v=area(1,3,5,0,0)
areas.append(v)
for v in areas:
print(
"Area of Circle:", v.areaofcircle(),\
"Area of Triangle:", v.areaoftriangl(),\
"Area of Rectangle:",v.areaofrectangle(),\
)

You are trying to declare radius inside an if elif statement,
v=area(1,3,5,0,0) at the if radius==0 and breath!=0: radius not declared at the elif length==0 and heigh!=0: also radius not declere the same happens and at elif height==0 and base!=0: Example if use v=area(0,3,5,0,0) radius to 0 self.radius declared successfully

what do you mean? where should I declare radius? and is it only problem for radius or other parameters like length and etc..

BTW: what should the variable "breath" mean?
How long you can stay under water?
I assume you mean "width" ;-)

does the code wich you use are the same code with you have provide if yes your post subject
AttributeError: 'area' object has no attribute 'areaofcircle' else please paste the code wich you use and get this AttributeError
RE: AttributeError: 'area' object has no attribute 'areaofcircle' - shane1236 - Aug-02-2019
@cvsae, Thanks for your help, well, I'm curious to know why should we put radius=0, and if i we don't then how to handle the problem.
Thanks
