Here is my homework: http://courses.missouristate.edu/JamilSaquer/CSC131/HOMEWORK/hw2_Circle2D.html

Here is my code:

My code did not run, but I do not know what I fix this code. SO i need help.

thank you.

Explanation / Answer

There were lot of spelling mistakes, and _init_, _cmp should be __init__ and __cmp__. I have changed overridden methods too. Last two statements will fail because "Hello" is not of type circle.

import math

def distance(x1,y1,x2,y2):
return math.sqrt((x1 - x2)**2 + (y1 - y2)**2)
class Circle2D(object):
def __init__(self, x=0, y=0, r=0):
self._x = x
self._y = y
self._r = r
def __str__(self):
return("Circle with center" + "(" + "%0.0f" % (self._x) + ", "
+ "%0.0f" % (self._y) + ")" + "and radius " + "%0.0f" % (self._r))

def getX(self):
return self._x
def getY(self):
return self._y
def getRadius(self):
return self._r
def setx(self, x):
self._x = x
def sety(self, y):
self._y = y
def setRadius(self, r):
self._r = r
def getArea(self):
return math.pi * self._r ** 2
def getPerimeter(self):
return math.pi * self._r * 2
      
  

def containsPoint(self, x, y):
d = distance(x, y, self._x, self._y)
return d <= self._r

def contains(self, circle):
d = distance(self._x, self._y, circle._x, circle._y)
return d + circle._r <= self._r
def overlaps(self, circle):
return distance(self._x, self._y, circle._x, circle._y) <= self._r + circle._r
def __contains__(self, anotherCircle):
return self.contains(anotherCircle)
def __lt__(self, secondCircle):
return self.__cmp__(secondCircle) < 0
def __le__(self, secondCircle):
return self.__cmp__(secondCircle) <= 0
def __gt__(self, secondCircle):
return self.__cmp__(secondCircle) > 0
def __ge__(self, secondCircle):
return self.__cmp__(secondCircle) >= 0
def __cmp__(self, secondCircle):
if self._r > secondCircle._r:
return 1

else:
return 0
