You already have different handlers for different menus - that is
exactly what you're doing in your sample code. You're just doing
secondary dispatch - you have one menu event handler and you are
inspecting the menu title to determine where to go next. You can bind
the IDs directly and skip the seconday dispatch. Here's a sample:

import wx
class TFrame(wx.Frame):
    def __init__(self, parent):
        wx.Frame.__init__(self, parent)
        menu = wx.Menu("File")
        menu.Append(wx.NewId(), "Item")

        #submenu one
        sm = wx.Menu("Submenu1")
        id1, id2 = wx.NewId(), wx.NewId()
        sm.Append(id1, "Subitem 1")
        sm.Append(id2, "Subitem 2")
        self.Bind(wx.EVT_MENU, self.OnSubmenuOne, id=id1)
        self.Bind(wx.EVT_MENU, self.OnSubmenuOne, id=id2)
        menu.AppendMenu(wx.NewId(), "Submenu One", sm)

        sm = wx.Menu("Submenu2")
        id1, id2 = wx.NewId(), wx.NewId()
        sm.Append(id1, "Subitem 1")
        sm.Append(id2, "Subitem 2")
        self.Bind(wx.EVT_MENU, self.OnSubmenuTwo, id=id1)
        self.Bind(wx.EVT_MENU, self.OnSubmenuTwo, id=id2)
        menu.AppendMenu(wx.NewId(), "Submenu Two", sm)

        mb = wx.MenuBar()
        mb.Append(menu, "File")
        self.SetMenuBar(mb)


    def OnSubmenuOne(self, evt):
        print "Do something one"
    def OnSubmenuTwo(self, evt):
        print "Do something two"


if __name__ == '__main__':
    app = wx.App(False)
    f = TFrame(None)
    f.Show()
    app.MainLoop()
