[已解决]我想实现Ratiobutton更新，结果失败，求解

你是巨猪怪_

代码如下所示，我想实现Radiobutton的替换，为什么这样替换不了呢？

1. from tkinter import *
   
2. 
   
3. x = 0
   
4. 
   
5. root = Tk()
   
6. 
   
7. answers = {}
   
8. answers[0] = [('草莓', 2), ('苹果', 3), ('西瓜', 5), ('菠萝', 10), ('橘子', 15)]
   
9. answers[1] = [('郊外', 2), ('电影院', 3), ('公园', 5), ('商场', 10), ('酒吧', 15), ('练歌房', 20)]
   
10. 
    
11. v = StringVar()
    
12. 
    
13. if x <= 14:
    
14.     if x == 0:
    
15.         for ans, point in answers[x]:
    
16.             choices1 = Radiobutton(root, text=ans, variable=v, value=point, padx=100, justify='left')
    
17.             choices1.pack()
    
18.     if x == 1:
    
19.         for ans, point in answers[1]:
    
20.             choices1 = Radiobutton(root, text=ans, variable=v, value=point, padx=100, justify='left')
    
21.             choices1.pack()
    
22. 
    
23. 
    
24. def point_plus_change():
    
25.     global x
    
26.     x += 1
    
27. 
    
28. 
    
29. butt_addpoint = Button(root, text='确定', font=('黑体', 10), command=point_plus_change)
    
30. butt_addpoint.pack()
    
31. 
    
32. 
    
33. root.mainloop()
