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:

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

Note: Unlike the co-ordinate system you may have encountered before, y, in this question, increases as you move vertically downwards. Example: Be careful to get the spacing right for str - i.e. comma followed by space.
>>> r = rectangle((2,3), 5, 6)
>>> str(r)
'((2, 3),(7, 9))'
>>> r.move((5,5))
>>> str(r)
'((5, 5), (10, 11))'
>>> r.resize(1,1)
>>> str(r)
'((5, 5), (6, 6))'
>>> r.getBottomright()
(6, 6)


if any can help me with I would be thankful for him or her

actually I have no idea how to code it
but the out come of the program shoud be
>>> r = rectangle((2,3), 5, 6)
>>> str(r)
'((2, 3),(7, 9))'
>>> r.move((5,5))
>>> str(r)
'((5, 5), (10, 11))'
>>> r.resize(1,1)
>>> str(r)
'((5, 5), (6, 6))'
>>> r.getBottomright()
(6, 6)

A technical term for creating a class is 'declare'.

When you create a class you are declaring a class, and when you see a class in code it is a class declaration. Just thought you might want to know the lingo.

You must understand the question and logics first.

And as lrh9 said, and very good, you declare classes and define their functions.

class rectangle():

    def __init__(self, coords, sizex, sizey):
        self._startx, self._starty = coords
        self._sizex = sizex
        self._sizey = sizey

    def getBottomright(self):
        print '(%s, %s)' % (self._startx + self._sizex, self._starty + self._sizey)

    def move(self, pos):
        self._startx, self._starty = pos

    def resize(self, width, height):
        self._sizex = width
        self._sizey = height

    def __str__(self):
        return '((%s, %s), (%s, %s))' % (self._startx, self._starty, self._startx + self._sizex, self._starty + self._sizey)


r = rectangle((2, 3), 5, 6)
print str(r)

"""'((2, 3), (7, 9))'"""

r.move((5, 5))
print str(r)

"""'((5, 5), (10, 11))'"""

r.resize(1,1)
print str(r)

"""'((5, 5), (6, 6))'"""

r.getBottomright()

"""(6, 6)"""

Cheers and Happy coding.
