I'm having trouble debugging my code.
class Point:

def compare(self, other):

if (x1 == x2) and (y1 == y2):
return 0
found = False
while found == False:
if ((x1 // n) != (x2 // n)) or ((y1 // n) != (y2 // n)):
found = True
c1 = ((x1 // n), (y1 // n))
c2 = ((x2 // n), (y2 // n))
else:
if x1 >= n and x2 >= n:
x1 = x1 - n
x2 = x2 - n
if y1 >= n and y2 >= n:
y1 = y1 - n
y2 = y2 - n
n = n / 2
if c1 == (0, 1):
e1 = 1

e2 = 3
if c2 == (1, 0):
e2 = 4
if e1 > e2:
return 1
if e2 > e1:
return -1
def dist(self, other):

y = abs(self.y - other.y)
if x >= y:
return x
else:
return y

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.

The traceback needed to indented to be readable.

回答1:
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
change to:
trace = Point(x, y)
And pointSet.getpoints returns a list of tuples:
return [(i.x, i.y) for i in self.list]
change to
return self.list
Though this seems intentional, since self.list in pointSet is already a list of points. Are you sure you want them to be points?
