Restarting a Python Application

I don't know wxPython, but I was able to grab an example program and
adapt it to do what I think you are asking for.
Something like this:

[code]
#! /usr/bin/env python

from wxPython import wx

ID_EXIT  = 101
ID_RST   = 102

class MyFrame(wx.wxFrame):
    def __init__(self, parent, ID, title):
        wx.wxFrame.__init__(self, parent, ID, title,
                         wx.wxDefaultPosition, wx.wxSize(200, 150))
        self.CreateStatusBar()
        self.SetStatusText("This is the statusbar")

        menu = wx.wxMenu()
        menu.Append(ID_EXIT, "E&xit", "Terminate the program")
        menu.Append(ID_RST, "&Restart", "Restart the program")

        menuBar = wx.wxMenuBar()
        menuBar.Append(menu, "&File");

        self.SetMenuBar(menuBar)

        wx.EVT_MENU(self, ID_EXIT,  self.TimeToQuit)
        wx.EVT_MENU(self, ID_RST,  self.TimeToRestart)

    def TimeToQuit(self, e):
        self.Close(wx.true)

    def TimeToRestart(self, e):
        global restart
        restart = True
        self.TimeToQuit(e)


class MyApp(wx.wxApp):
    def OnInit(self):
        global restart
        restart = False
        frame = MyFrame(wx.NULL, -1, "Hello from wxPython")
        frame.Show(wx.true)
        self.SetTopWindow(frame)
        return wx.true

if __name__ == "__main__":
    MyApp(0).MainLoop()
    while restart:
        MyApp(0).MainLoop()
