Python Tkinter，GUI没有生成，没有错误显示

Question

请看附上的代码。我试图预先显示我的GUI，但没有出现，没有GUI，并且在命令窗口上没有错误。它应该是一个主窗口，然后是两个父框架，以及它们中的子框架。

import Tkinter as tkinter 


class successGUI: 

    def __init_(self): 

     #create main window 
     self.main_window = tkinter.Tk() 

     #create two mainframes 
     self.left_frame = tkinter.Frame() 
     self.right_frame = tkinter.Frame() 

     #create frames to group widgets 
     #left frame's 
     self.top_lframe = tkinter.Frame(self.left_frame) 
     self.lseparator1 = tkinter.Frame(self.left_frame,height=2, bd=1, relief='sunken') 
     self.path_frame = tkinter.Frame(self.left_frame) 
     self.output_frame = tkinter.Frame(self.left_frame) 
     self.lseparator2 = tkinter.Frame(self.left_frame,height=2, bd=1, relief='sunken') 
     self.load_frame = tkinter.Frame(self.left_frame) 
     self.start_frame = tkinter.Frame(self.left_frame) 
     self.lseparator3 = tkinter.Frame(self.left_frame) 
     self.status_frame = tkinter.Frame(self.left_frame) 
     self.lseparator4 = tkinter.Frame(self.left_frame) 

     #right frame's 
     self.top_rframe = tkinter.Frame(self.right_frame) 

     #create widgets for the top frame 
     self.title_label = tkinter.Label(self.top_lframe, text = 'Title??', font = 14) 
     self.ghost_label = tkinter.Label(self.top_lframe, width = 50, height = 2) 
     #pack the top frame's widget 
     self.title_label.pack() 
     self.ghost_label.pack()

     #pack the output frame's widgets 
     self.output_label.pack(side='left') 
     self.output_entry.pack(side='left')

     self.ghost_label3 = tkinter.Label(self.load_frame, width = 10, height=1) 

     #pack the start frame's widgets 
     self.start_button.pack() 
     self.ghost_label3.pack() 

     #create the widgets for the status frame 
     self.status = tkinter.Label(self.status_frame,text = 'Status:', width = 15) 
     self.status_bar = tkinter.Label(self.status_frame, bd=1, 
             relief='sunken', anchor='w',width = 5, 
             textvariable = self.value)

     tkinter.mainloop() 

     def start(self): 
      print ('yeap') 

succes = successGUI()

您没有在两侧为两个下划线命名初始化程序。其次，你使用了甚至不存在的函数。例如，

self.load_button = tkinter.Button(self.load_frame, text = 'Load', 
              command=self.load) 

我没有在任何地方看到self.load函数。调试是一项重要的技能，您应该花时间学习。
