问题描述
我在调试代码时遇到问题。
I'm having trouble debugging my code.

当我尝试运行测试时，大多数返回一个错误，提示 tuple对象具有没有属性 getx。我不确定为什么会继续出现此错误。这是我的测试代码。
When I try and run my tests, most of them come back with an error saying 'tuple' object has no attribute 'getx'. I'm not sure why this error keeps coming up. Here is my test code.

回溯必须缩进以便可读。
The traceback needed to indented to be readable.
Traceback:

推荐答案
pointset.NN返回一个元组，因此nn是元组，在此处设置：
pointset.NN returns a tuple, so nn is tuple, set here:
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)
pointpoint.getpoints返回一个元组列表：
And pointSet.getpoints returns a list of tuples:
return [(i.x, i.y) for i in self.list]
更改为
return self.list
尽管这似乎是故意的，因为pointSet中的self.list已经是一个点列表。您确定要让它们成为积分吗？
Though this seems intentional, since self.list in pointSet is already a list of points. Are you sure you want them to be points?
