(TAinter two rectangles intersect?) Using the Rectangle2D class you defined in Exercise 8.19, write a program that enables the user to specify the location and size of the rectangles and displays whether the two rectangles intersect, as shownExplanation / Answer
class Rectangle(object):
def __init__(self, width = 1, height = 2):
self.width = width
self.height = height
def Perimeter(self):
"Return the Perimeter of the rectangle"
return (2 * self.width) + (2 * self.height)
def Area(self):
"Return the area of the rectangle"
return self.width * self.height
print("Enter your values")
width = 0
height = 0
# read in the input and see if it will convert to int values
# if not, repeat
while width == 0 or height == 0:
try:
width = int(input("width " ""))
height = int(input("height " ""))
except:
width = height = 0
R1 = Rectangle(width, height)
print ('R1:', R1.Perimeter(), R1.Area())
