Question

Urgent!

Consider the following code for the point class studied in week 2: Import math class Point: #static attribute _count = 0 # to count how many points we have created so far # initialization method def _init__(self, x = 0, y = 0): #default arguments technique self._x = x self._y=y Point_count += 1 #updating the point count #updating the Point count #getters def getX(self): return self._x def getY(self): return self._y def printPoint(self): return " + str(self._x)+ ' ' + str(self._y)+") # setters def setPoint(self, x, y): self._x= x self._y=y def reset(self): self.setPoint(0, 0) # other methods def distance(self, p): return math.sqrt((self.getX() - P.getX() ** 2 + (self.getY() .p.getY() ** 2) # static method @staticmethod def printPointCount(): return Point

Program

import math
class Point:
#static attribute
__count=0 #to count how many points we have created so far
#initialization method
def __init__(self,x=0,y=0): #defaults arguments technique
self.__x=x
self.__y=y
Point.__count+=1 #updating the point count
#getters
def getX(self):
return self.__x
def getY(self):
return self.__y
def printPoint(self):
return '('+str(self.__x)+','+str(self.__y)+')'
#setters
def setPoint(self,x,y):
self.__x=x
self.__y=y
def reset(self):
self.setPoint(0,0)
#other methods
def distance(self,p):
return math.sqrt((self.getX()-p.getX())**2 + (self.getY()-p.getY())**2)
#static method
def printPointCount():
return Point.__count
def getSlope(self,p): #method to find slope
return ((p.getY()-self.getY())/(p.getX()-self.getX()))
#testing
#creating two Point objects
p1=Point(3,4)
p2=Point(8,6)
print("Slope is ",p1.getSlope(p2)) #calling slope method

Output

Slope is 0.4
