下面的代码由于某种原因给了我一个错误,有人可以告诉我会是什么问题..
基本上,我创建了 2 个类 Point & Circle..The circle 试图继承 Point 类。
Code:
class Point():
x = 0.0
y = 0.0
def __init__(self, x, y):
self.x = x
self.y = y
print("Point constructor")
def ToString(self):
return "{X:" + str(self.x) + ",Y:" + str(self.y) + "}"
class Circle(Point):
radius = 0.0
def __init__(self, x, y, radius):
super(Point,self).__init__(x,y)
self.radius = radius
print("Circle constructor")
def ToString(self):
return super().ToString() + \
",{RADIUS=" + str(self.radius) + "}"
if __name__=='__main__':
newpoint = Point(10,20)
newcircle = Circle(10,20,0)
错误:
C:\Python27>python Point.py
Point constructor
Traceback (most recent call last):
File "Point.py", line 29, in <module>
newcircle = Circle(10,20,0)
File "Point.py", line 18, in __init__
