Creating A Python Rectangle Object Class That Can Print The Corner Coordinates

I am new to python. I need to create a python Rectangle object class that when called upon one can print the coordinates of the corners as well as have the area and perimeter. I am

Solution 1:

try this:

def__repr__(self):
        return'tL = '+str(self.tL) + ', tR ='+ str(self.tR)+', bL ='+ str(self.bL) + ', bR =' +str(self.bR)

notes:

• make only one return statement execute in a function, in your code your function only returns self.bT (the last).
• In the provided code def __repr__(self) is not indented.
• you don't need 4 points to define a rectangle.
• your Rectangle corners shouldn't just be integers, they have to be sequences of two coordinates (x, y) for instance (3, 7) is a point, implement a point as a 2 integers tuple or list.

edit: as the OP asked, here's how to change your __init__ method to work with cartesian coordinates:

classRectangle:
    def__init__(self, tL, bR):  #tL and bR should be passed as tuples
        self.tL = tL
        self.tR = (bR[0], tL[1])  #access tuple elements with tuple[index]
        self.bL = (bR[1], tL[0])
        self.bR = bR

        self.width = bR[0]- tL[0]
        self.height = bR[1] - tL[1]
    defarea(self):
        #get area#...defperim(self):
        #get perim#...

r1 = Rectangle((5,5), (30, 20))
print r1.tL   #output (5, 5)print r1.tR   #output (30, 5)print r1.width #output 25print r1.area() #output 375

of course you can create a Point class instead of that, and then you pass two Points to __init__ to define the rectangle.

I hope that helped you!

Solution 2:

First of all, functions cannot have more than one return statement.

Also, def __repr__(self): is not correctly indented (it belongs to the Rectangle class).

You might prefer __str__ over __repr__, see https://docs.python.org/2/reference/datamodel.html#object.repr for more details.

classRectangle:
    def__init__(self, topLeft, topRight, bottomLeft, bottomRight):
        self.tL = topLeft
        self.tR = topRight
        self.bL = bottomLeft
        self.bR = bottomRight
    defperim(self):
        return (2 * (self.tL + self.tR)) + (2 * (self.bL + self.bR))
    defarea(self):
        return (self.tL + self.tR) * (self.bL + self.bR)
    defposition(self):
        return (self.tL, self.tR, self.bL, self.bR)
    def__str__(self):
        return"Rectangle(%s, %s, %s, %s)" % (self.tL, self.tR, self.bL, self.bR)

r1 = Rectangle (5, 5, 10, 10)
print r1
print"Perimeter: %s" % r1.perim()
print"Area: %s" % r1.area()
print"Position: (%s, %s, %s, %s)" % r1.position()
