wxPython: how to create a bash shell window?

Question

I want to create a popup window using wxPython that acts like a bash shell. I don\'t want a terminal emulator, I don\'t need job control, I just want a REPL (Read, Eval, Pr

i searched but there doesn't seem to be any exiting bash shell for wxPython though wx.py module has Shell module which is for python interpretor good thing is you can pass your own interpretor to it,so I have come with very simple bash interpreter. example currently reads only one line from bash stdout, otherwise it will get stuck, in real code you must read output in thread or use select

import wx
import wx.py
from subprocess import Popen, PIPE

class MyInterpretor(object):
    def __init__(self, locals, rawin, stdin, stdout, stderr):
        self.introText = "Welcome to stackoverflow bash shell"
        self.locals = locals
        self.revision = 1.0
        self.rawin = rawin
        self.stdin = stdin
        self.stdout = stdout
        self.stderr = stderr

        #
        self.more = False

        # bash process
        self.bp = Popen('bash', shell=False, stdout=PIPE, stdin=PIPE, stderr=PIPE)


    def getAutoCompleteKeys(self):
        return [ord('\t')]

    def getAutoCompleteList(self, *args, **kwargs):
        return []

    def getCallTip(self, command):
        return ""

    def push(self, command):
        command = command.strip()
        if not command: return

        self.bp.stdin.write(command+"\n")
        self.stdout.write(self.bp.stdout.readline())

app = wx.PySimpleApp()
frame = wx.py.shell.ShellFrame(InterpClass=MyInterpretor)
frame.Show()
app.SetTopWindow(frame)
app.MainLoop()
