如何将python控制台输出嵌入到wxPython中

import wx
import sys
from io import StringIO

class ConsoleRedirector:
    def __init__(self, text_ctrl):
        self.text_ctrl = text_ctrl
        self.stdout = sys.stdout
        self.stderr = sys.stderr
        self.string_io = StringIO()

    def write(self, message):
        self.string_io.write(message)
        self.text_ctrl.SetValue(self.string_io.getvalue())
        self.text_ctrl.ShowPosition(self.text_ctrl.GetLastPosition())

    def flush(self):
        pass

    def redirect(self):
        sys.stdout = self
        sys.stderr = self

    def restore(self):
        sys.stdout = self.stdout
        sys.stderr = self.stderr

class MainWindow(wx.Frame):
    def __init__(self, parent, title):
        super(MainWindow, self).__init__(parent, title=title, size=(800, 600))
        panel = wx.Panel(self)
        sizer = wx.BoxSizer(wx.VERTICAL)
        self.text_ctrl = wx.TextCtrl(panel, style=wx.TE_MULTILINE | wx.TE_READONLY)
        sizer.Add(self.text_ctrl, proportion=1, flag=wx.EXPAND)
        panel.SetSizer(sizer)
        self.Show()

if __name__ == '__main__':
    app = wx.App()
    frame = MainWindow(None, "Python Console")
    redirector = ConsoleRedirector(frame.text_ctrl)
    redirector.redirect()
    app.MainLoop()
    redirector.restore()
