PYTHON 一个程序，23行有错，不明白为什么 敬请指教！

Python code:


class Rectangle:
def __init__(self, width, height):
self.width = width
self.height = height
def paint(self, factory):
point = factory.getPoint()
corner = factory.getCorner()
corner.leftUp()
point.line(self.width - 2)
corner.rightUp()
print()
for i in range(self.height - 2):
point.line(self.width)
print()
corner.leftDown()
point.line(self.width - 2);
corner.rightDown();
print()

class Dot:
def line(self, width):
for i in range(width):
print("-",end="")
class Sharp:
def leftUp(self):
print("#", end="")
def rightUp(self):
print("#", end="")
def leftDown(self):
print("#", end="")
def rightDown(self):
print("#", end="")

class DotSharpFactory:
def getPoint(self):
return Dot()
def getCorner(self):
return Sharp()

rect = Rectangle(20, 10)
rect.paint(DotSharpFactory())

23行有错，不明白为什么 敬请指教！

也就是 这一句 print("-",end="") 指在 “＝” 这里有问题

觉得python 3下应该不会错。我是用2.6的，print当函数用要
