函数的print输出要在gui界面显示，请问要怎么搞丫
下附我参考进行修改的代码，可以改成不是类的么，虽说我其实看不懂
import tkinter as tk
import sys
class ExampleApp(tk.Tk):
def __init__(self):
super(ExampleApp, self).__init__()
toolBar = tk.Frame(self)
toolBar.pack(side=tk.TOP, fill=tk.X)
button1 = tk.Button(self, text='打印乘法表', command=self.print_stdout)
button1.pack(in_=toolBar, side=tk.BOTTOM)
self.text = tk.Text(self, wrap='word')
self.text.pack(side=tk.TOP, fill=tk.BOTH, expand=True)
sys.stdout = TextRedirector(self.text)
def print_stdout(self):
for i in range(1, 10):
for j in range(1, i + 1):
print('%s*%s=%s' % (i, j, i * j), end=' ')
print()
class TextRedirector(object):
def __init__(self, widget, tag='stdout'):
self.widget = widget
self.tag = tag
def write(self, str):
self.widget.configure(state='normal')
self.widget.insert(tk.END, str, (self.tag,)) # (self.tag,) 是设置配置
self.widget.configure(state='disabled')
if __name__ == '__main__':
app = ExampleApp()
app.mainloop()
我目前的代码，改了很久，但是还是在gui打印不出来乘法表

tk.widget.configure(state='disabled')
