Question

我正在尝试在Python中创建GUI但由于某种原因它无法正常工作。 GUI应该有一个信息按钮和一个退出按钮。我知道这是一个简单的错误，我应该能够调试，但我无法找到它。

回溯错误消息：

在       区= GUI（）

self.info_button = tkinter.Button（self.bottom_frame，text =＆＃34; Show Info＆＃34;，   command = self.showinfo）AttributeError：＆＃39; GUI＆＃39;对象没有属性   ＆＃39; showinfo＆＃39;

这是我的代码：

import tkinter
import tkinter.messagebox

class GUI:
   def __init__(self):

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

        #create two frames
        self.top_frame= tkinter.Frame()
        self.bottom_frame = tkinter.Frame()

        #object of StringVar class
        self.value = tkinter.StringVar()

        #top frame label
        self.info_label = tkinter.Label(self.top_frame,textvariable = self.value)

        #information button that displays the information about the name and address
        self.info_button = tkinter.Button(self.bottom_frame, text="Show Info", command=self.showinfo)

        #quit button that closes the program
        self.quit_button = tkinter.Button(self.bottom_frame, text ='Quit', command=self.main_window.destroy)

        #pack method for packing widgets
        self.info_label.pack()
        self.info_button.pack(side='left')      
        self.quit_button.pack(side='left')

        self.top_frame.pack()
        self.bottom_frame.pack()

        #main loop for running the program
        tkinter.mainloop()

def showinfo(self):
    inf = '\tSteven Marcus\n\t274 Baily Drive\n\tWaynesville, NC 27999'
    self.value.set(inf)

#call the main function
gu=GUI()

Python中的缩进非常重要，缩进是关闭的，您需要缩进整个def showinfo(self):块，以便它位于GUI类之下。

import tkinter
import tkinter.messagebox

class GUI:
   def __init__(self):

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

        #create two frames
        self.top_frame= tkinter.Frame()
        self.bottom_frame = tkinter.Frame()

        #object of StringVar class
        self.value = tkinter.StringVar()

        #top frame label
        self.info_label = tkinter.Label(self.top_frame,textvariable = self.value)

        #information button that displays the information about the name and address
        self.info_button = tkinter.Button(self.bottom_frame, text="Show Info", command=self.showinfo)

        #quit button that closes the program
        self.quit_button = tkinter.Button(self.bottom_frame, text ='Quit', command=self.main_window.destroy)

        #pack method for packing widgets
        self.info_label.pack()
        self.info_button.pack(side='left')      
        self.quit_button.pack(side='left')

        self.top_frame.pack()
        self.bottom_frame.pack()

        #main loop for running the program
        tkinter.mainloop()

   def showinfo(self): # indent these:
        inf = '\tSteven Marcus\n\t274 Baily Drive\n\tWaynesville, NC 27999'
        self.value.set(inf)

#call the main function
gu=GUI()
