我使用Pywin32库。 以下代码段最多可读取6行和19列。如果我尝试阅读更多IDLE ppython gui（32位）似乎正在循环中。程序既不退出也不给我一个错误。 这是正确的行为吗？
以下是代码：
import tkinter as tk
from win32com.client import Dispatch
from tkinter import *
#from tkinter import ttk
#import tkinter
class Example(tk.Frame):
def __init__(self, root):
root.title('AAAA')
tk.Frame.__init__(self, root, width=0, height=0)
self.canvas = tk.Canvas(root, width=1000, height=550) #grandezza finestra
self.frame = tk.Frame(self.canvas)
self.vsb = tk.Scrollbar(root, orient="horizontal", command=self.canvas.xview)
self.canvas.configure(xscrollcommand=self.vsb.set)
self.vsb.pack(side="bottom", fill="x")
self.canvas.pack(side="top", fill="both", expand=True)
self.canvas.create_window((4,4), window=self.frame, anchor="nw",
tags="self.frame")
self.vsb = tk.Scrollbar(root, orient="vertical", command=self.canvas.yview)
self.canvas.configure(yscrollcommand=self.vsb.set)
self.vsb.pack(side="right", fill="y")
self.canvas.pack(side="left", fill="both", expand=True)
self.canvas.create_window((4,4), window=self.frame, anchor="nw",
tags="self.frame")
self.titoli_HFT = ["1", "1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","9"]
for i in range (0,len(self.titoli_HFT)):
self.lblnome=tk.Label(self.frame, text= self.titoli_HFT[i], font=("Helvetica", 8))
self.lblnome.grid(row=2, column=i+1, padx=5, pady=15) #place(x=85+j, y=50)
self.frame.bind("<Configure>", self.onFrameConfigure)
self.lettura()

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

wbH.Close()

我哪里错了？
