这是我的程序(一个非常简单的程序):

from math import sqrt
class Point:
x = 0;
y = 0;
def __init__(self, x, y):
self.x = x
self.y = y
def __eq__(self, other):
return self.__dict__ == other.__dict__
def get_dist(self, other):
return sqrt(abs((self.x - other.x)^2 + (self.y - other.y)^2))
def is_rect(self,other,another,yet_another):
return (self.get_dist(other) == another.get_dist(yet_another)) and \
(self.get_dist(another) == other.get_dist(yet_another)) and \
(self.get_dist(yet_another) == other.get_dist(another))
a, b, c, d = Point(4,3),Point(4,9), Point(7,3), Point(7,9)
if a.is_rect(b,c,d):
print "Rectangle."
else:
print "No, not a rectangle!"
这返回没有。一个用 Java 编写的类似程序会返回预期的答案。
我对 Python很陌生。帮助!
