Question

Defining a Class

Define the class Rectangle. It’s constructor takes a pair of numbers representing the top-left corner, and two other numbers representing the width and height. It has the following methods:

• get_bottom_right() - return the bottom right corner as a pair of
  numbers.
• move(p) - move the rectangle so that p becomes the top-left corner
  (leaving the width and height unchanged).
• resize(width, height) - set the width and height of the rectangle
  to the supplied arguments (leaving the top-left corner unchanged).
• __str__() - return the string representation of the rectangle as a
  pair of pairs - i.e. the top left and bottom right corners.

Note: this problem uses the coordinate system commonly used for computer graphics. In this system, the origin is in the top-left corner and the y-axis is flipped. The bottom-right corner will therefore have a larger y coordinate than the top-left corner.

Examples:
Each example below follows on from the previous one. Be careful to get the spacing right for str - i.e. comma followed by space.

>>> r = Rectangle((2,3), 5, 7)
>>> str(r)
'((2, 3), (7, 10))'
>>> r.move((5,6))
>>> str(r)
'((5, 6), (10, 13))'
>>> r.resize(2,3)
>>> str(r)
'((5,6), (7, 9))'
>>> r.get_bottom_right()
(7, 9)

Answer 1

class Rectangle:
  
def __init__(self, top_left, width, height):
self.top_left = top_left
self.width = width
self.height = height
  
def get_bottom_right(self):
bottom_right=[0, 0]
bottom_right[0] = self.top_left[0] + self.width
bottom_right[1] = self.top_left[1] + self.height
return (bottom_right[0], bottom_right[1])
  
def move(self, p):
self.top_left = p
  
def resize(self, width, height):
self.width = width
self.height = height
  
def __str__(self):
bottom_right = self.get_bottom_right()
return str((self.top_left, self.get_bottom_right()))

The class definition is quite self-explanatory. Please go through it, and let me know if you need any further clarifications.
