Question

我正在从“ Programming Python”一书中学习tkinter。在滚动条专用部分中，我遇到了无法修复的问题。

from tkinter import *

class ScrolledList(Frame):
    def __int__(self, options, parent=None):
        Frame.__init__(self, parent)
        self.pack(expand=YES, fill=BOTH)
        self.makeWidgets(options)

    def hendleList(self, event):
        index=self.listbox.curselection()
        label=self.listbox.get(index)
        self.runCommand(label)

    def makeWidget(self, options):
        sbar=Scrollbar(self)
        list=Listbox(self, relief=SUNKEN)
        sbar.config(command=list.yview)
        list.config(yscrollcommand=sbar.set)
        sbar.pack(side=RIGHT, fill=Y)
        list.pack(side=LEFT, expand=YES, fill=BOTH)
        pos=0
        for label in options:
            list.insert(pos, label)
            pos+=1
        list.bind('<Double-1>', self.handleList)
        self.listbox = list

    def runCommand(self, selection):
        print('You selected:', selection)

if __name__ == '__main__':
    options=[('Luberjack-{}'.format(x)) for x in range(20)]
    ScrolledList(options).mainloop()

这是我的代码，并且出现了错误：

Traceback (most recent call last):
File "C:/Users/User/PycharmProjects/untitled3/venv/scr_list.py", line 34, in <module>
ScrolledList(options).mainloop()
File "C:\Python37-32\lib\tkinter\__init__.py", line 2741, in __init__
Widget.__init__(self, master, 'frame', cnf, {}, extra)
File "C:\Python37-32\lib\tkinter\__init__.py", line 2289, in __init__
BaseWidget._setup(self, master, cnf)
File "C:\Python37-32\lib\tkinter\__init__.py", line 2259, in _setup
self.tk = master.tk
AttributeError: 'list' object has no attribute 'tk'

以前也有类似的问题，但是我已经在代码中调用了Frame __init__

存在一些拼写错误：def __int__，makeWidget和hendleList。经过更正后，它可以正确运行：

from tkinter import *

class ScrolledList(Frame):
    def __init__(self, options, parent=None):
        Frame.__init__(self, parent)
        self.pack(expand=YES, fill=BOTH)
        self.makeWidgets(options)

    def handleList(self, event):
        index=self.listbox.curselection()
        label=self.listbox.get(index)
        self.runCommand(label)

    def makeWidgets(self, options):
        sbar=Scrollbar(self)
        list=Listbox(self, relief=SUNKEN)
        sbar.config(command=list.yview)
        list.config(yscrollcommand=sbar.set)
        sbar.pack(side=RIGHT, fill=Y)
        list.pack(side=LEFT, expand=YES, fill=BOTH)
        pos=0
        for label in options:
            list.insert(pos, label)
            pos+=1
        list.bind('<Double-1>', self.handleList)
        self.listbox = list

    def runCommand(self, selection):
        print('You selected:', selection)

if __name__ == '__main__':
    options=[('Luberjack-{}'.format(x)) for x in range(20)]
    ScrolledList(options).mainloop()

AttributeError：“列表”对象没有属性“ tk”
