当我尝试运行我的测试时，他们中的大多数人都会回来时发出一个错误，说“＆＃39; tuple＆＃39;对象没有属性＆＃39; getx＆＃39;。我不确定为什么这个错误会不断出现。这是我的测试代码。

答案 0 :(得分：0)
pointset.NN返回一个元组，所以nn是元组，设置在这里：
for x,y in self.getpoints():
if query.dist(Point(x, y)) < count:
count = query.dist(Point(x, y))
trace = (x, y) # TRACE IS A TUPLE
return trace
更改为：
trace = Point(x, y)
pointSet.getpoints返回元组列表：
return [(i.x, i.y) for i in self.list]
更改为
return self.list
虽然这似乎是故意的，因为pointSet中的self.list已经是一个点列表。你确定要他们成为积分吗？
