Tkinter长列表显示在网格中

Question

我有一个巨大的列表l1里面有近1074个应用程序名称

['10 Best Foods for You' '104 找工作 - 找工作 找打工 找兼職 履歷健檢 履歷診療室' '11st' ...
 'Hotwire Hotel & Car Rental App' 'Housing-Real Estate & Property'
 'Houzz Interior Design Ideas'] 

我想在下面相同的窗口中显示所有应用程序，但它们都不可见。

我在控制台中遇到以下错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\ProgramData\Anaconda3\lib\tkinter\__init__.py", line 1705, in __call__
    return self.func(*args)

    (widgetName, self._w) + extra + self._options(cnf))
_tkinter.TclError: character U+1f602 is above the range (U+0000-U+FFFF) allowed by Tcl

我的代码：

        qy14apps = Toplevel(screen2)
        qy14apps.title("Select one app")
        adjustWindow(qy14apps) # configuring the window
        l1=list_apps()
        print (len(l1))
        def onFrameConfigure(canvas):

            canvas.configure(scrollregion=canvas.bbox("all"))

        def populate(frame):

            for i in range(len(l1)):
                tk.Label(frame, text=l1[i], width='80',anchor=W,relief=GROOVE, height="4", font=("Calibri", 10, 'bold'), fg='black', bg='Green',wraplength=500).grid(row=i,column=0,sticky=W)
                #l2=Label(text="\n", bg='white')
                #l2.grid(row=i+1,column=0)
                tk.Button(frame, text='Select app', width='15', font=("Open Sans", 13, 'bold'), bg='brown', fg='white',command="").grid(row=i,column=1,sticky=W)

        canvas = tk.Canvas(qy14apps, borderwidth=0, background="#ffffff")
        frame = tk.Frame(canvas, background="#ffffff")
        vsb = tk.Scrollbar(qy14apps, orient="vertical", command=canvas.yview)
        canvas.configure(yscrollcommand=vsb.set)

        vsb.pack(side="right", fill="y")
        canvas.pack(side="left", fill="both", expand=True)
        canvas.create_window((4,4), window=frame, anchor="nw")

        frame.bind("<Configure>", lambda event, canvas=canvas: onFrameConfigure(canvas))
        populate(frame)

我不明白我哪里出错了，是不是因为名单太多了？ 我已经将同样的概念应用于20个元素的列表，然后它就起作用了。 任何帮助都是值得赞赏的。谢谢

我宁愿将大量数据插入一个列表框，并将按钮链接到一个函数，该函数通过listbox变量检索所选列表项

listboxvariablename.curselection()

要删除花括号，您可以绕过每个列表框条目，在将列表插入列表框之前循环列表，并通过其索引引用该条目。这将在将条目插入列表框时去掉大括号
