[英]Tkinter getting the average of coordinates
I have looked up similiar topics but couldn't find an answer to the problem I have been dealing with.我查找了类似的主题,但找不到我一直在处理的问题的答案。 Let me completely explain the situation.让我完整地解释一下情况。
I have made a python GUI with ovals and I want to get the coordinates of these ovals.我用椭圆制作了一个 python GUI,我想获得这些椭圆的坐标。 When they are tagged.当它们被标记时。
I have been successful on getting coordinates, but it seems tkinter gives me 4 values (x1,x2,y1,y2).我已经成功获得坐标,但似乎 tkinter 给了我 4 个值(x1、x2、y1、y2)。 To which I prefer having only x and y coordinates.我更喜欢只有 x 和 y 坐标。
As I have consulted another topic to solve this problem, I have been made clear that I haven't myself clear.由于我已经咨询了另一个主题来解决此问题,因此我已明确表示我自己还不清楚。 And my question was just confusing.我的问题只是令人困惑。
So I have 92 ovals and I want to get only x and ys using coordinate function.所以我有 92 个椭圆,我只想使用坐标函数得到 x 和 ys。
Here is the complete code( I have deleted unnecessary details.这是完整的代码(我删除了不必要的细节。

Stop button runs the function.停止按钮运行该功能。 Let me explain what is wrong with it with numbers.让我解释一下数字有什么问题。 When object 1 is selected the coordinates are true.选择对象1时,坐标是真的。 For example when I choose only object 1, I get :例如,当我只选择对象 1 时,我得到:
[25.0,25.0]
And when I choose only object 2, I get:当我只选择对象 2 时,我得到:
[40.0,75.0]
But when I choose both of these objects together, I get:但是当我同时选择这两个对象时,我得到:
[25.0, 25.0, 32.5, 50.0, 40.0, 75.0]
As you can see there are unnecessary values.如您所见,存在不必要的值。 I want to get 2 values from each object, any help would be appreciated.我想从每个对象中获取 2 个值,任何帮助将不胜感激。
You should calculate the center x, y for every 4 items in liste6
:您应该为liste6
每 4 个项目liste6
x, y :
for i in range(0, len(liste6), 4):
output.append((liste6[i] + liste6[i+2])/2) # center x
output.append((liste6[i+1] + liste6[i+3])/2) # center y
