Problem beim Starten wx.dialog in Wx Python

Question

Ich bin neu in Python. Ich fing an, wx Python zu benutzen, um eine GUI zu verursachen. GUI hat einen Hauptrahmen. Hauptrahmen hat Knopf sagen START. Wenn ich auf den Button klicke, erscheint ein weiteres Fenster mit einigen Kontrollkästchen. Aber ich bekomme Fehler. Unten ist der Code

import wx 
import re 

class MyFrame(wx.Frame): 
    i = 1 
    def __init__(self): 
     wx.Frame.__init__(self, None, -1, "My Frame", size=(3000, 3000)) 
     panel = wx.Panel(self) 
     #panel.Bind(wx.EVT_MOTION, self.OnMove) 
     wx.StaticText(panel, -1, "What are the values of X", pos=(10, 12)) 
     startButton=wx.Button(panel,label="Start",pos=(800, 400), size = (50,50)) 
     self.Bind(wx.EVT_BUTTON, self.start, startButton) 
     txt = open("questions.txt") 
     dict = {} 
     alist = [] 

     for line in txt:  
      if re.search("^\n", line): continue 
      searchObj = re.search("([\d]+)\.\s*(.*)", line) 
      if searchObj : 
       i = searchObj.group(1) 
       j = 1 
       key = 'Q' + str(i) 
       dict[key] = [searchObj.group(2)] 
      searchObj2 = re.search("[^0-9]+\.\s*(.*)", line) 
      if searchObj2 : 
       dict[key,j] = (searchObj2.group(1)) 
       j = j + 1 
     dict['totalQuestions'] = i 
     txt.close() 
     print dict 
    def newwindow(self, event): 
     dia = MyDialog(self, -1, 'buttons', "true") 
     dia.ShowModal() 
     dia.Destroy() 
    def start(self, event): 
     dictIndex = self.i 
     start = MyQuestionDialog(self, -1, "button", dictIndex, dict) 
     start.ShowModal() 
     start.Destroy() 
     dictIndex = dictIndex + 1 





class MyQuestionDialog(wx.Dialog): 
    def __init__(self, parent, id, title, dictIndex, dict): 
     wx.Dialog.__init__(self, parent, id, title, size=(1000,1000)) 
     # panel1 = wx.Panel(self, -1) 
     key = 'Q' + str(dictIndex) 
     # wx.StaticText(panel, -1, dict[key], pos=(10, 12)) 
     #self.posCtrl = wx.TextCtrl(panel, -1, "", pos=(100, 10)) 
     wx.CheckBox(self, -1, dict[key,1], (20,100), (160,-1)) 
     # self.getValue = self.option1.GetValue() 
     wx.CheckBox(self, -1, dict[key,2], (20,150), (160,-1)) 
     wx.CheckBox(self, -1, dict[key,3], (20,200), (160,-1)) 
     wx.CheckBox(self, -1, dict[key,4], (20,250), (160,-1)) 
     button=wx.Button(self,label="OK",pos=(800, 400), size = (50,50)) 
     # self.Bind(wx.EVT_BUTTON, self.newwindow, button) 
     nextButton=wx.Button(self,label="Next",pos=(1000, 400), size = (50,50)) 
     # self.Bind(wx.EVT_BUTTON, self.nextwindow, nextButton) 



class MyDialog(wx.Dialog): 
    def __init__(self, parent, id, title, answer): 
     wx.Dialog.__init__(self, parent, id, title, size=(350,300)) 
     wx.StaticText(self, -1, answer , pos=(10, 12)) 


app = wx.App(False) 
frame = MyFrame() 
frame.Show(True) 
app.MainLoop() 

Nach Fehler Ich bin immer

Traceback (most recent call last): 
    File "3_phase.py", line 39, in start 
    start = MyQuestionDialog(self, -1, "button", dictIndex, dict) 
    File "3_phase.py", line 55, in __init__ 
    wx.CheckBox(self, -1, dict[key,1], (20,100), (160,-1)) 
TypeError: 'type' object has no attribute '__getitem__' 

Answer 1

Sie verwenden dict als Argument/Variablennamen, aber dict ist ein reservierter Name für das Wörterbuch Klasse in Python. Versuchen Sie, etwas anderes zu benennen.
