Seems to work fine here (select File->Exit, program exits - or were you
expecting something else?).  Could you be more specific than "doesn't
work"?.  Do you have a problem with your indentation?

Use wxTextCtrl.GetValue() (see below).

I've made several minor modifications to your source.  Note the use of
wxNewId() rather than explicit id's.  It's better to let wxPython manage
the id's that your program uses.  Far less prone to error.  I also got
sort of carried away and did some other stuff ;)  Anyway, I this seems
to work for me:

import sys, os
from   wxPython.wx import *

ID_OPEN = wxNewId()
ID_SAVE = wxNewId()
ID_EXIT = wxNewId()

class main_window(wxFrame):
    def __init__(self, parent, id, title):
        wxFrame.__init__(self, parent, -1, title, size = (500,500),
                        
style=wxDEFAULT_FRAME_STYLE|wxNO_FULL_REPAINT_ON_RESIZE)
            
        self.CreateStatusBar()
        self.SetStatusText("small editor")
        
        M_file = wxMenu()
        M_file.Append(ID_OPEN, "&Open","Open a file")
        M_file.Append(ID_SAVE, "&Save","Save a file")
        M_file.Append(ID_EXIT, "&Quit","Quit this small editor")
        
        menuBar = wxMenuBar()
        menuBar.Append(M_file,"&File")
        self.SetMenuBar(menuBar)

        self.path = None
        self.control = wxTextCtrl(self, -1, style=wxTE_MULTILINE)
        self.Show(true)
        
        EVT_MENU(self, ID_EXIT,  self.OnExit)
        EVT_MENU(self, ID_SAVE,  self.OnSave)
        
    def OnExit(self, event):
        self.Close(true)
                                
    def OnSave(self, event):
        text = self.control.GetValue()
        if self.path is None:
            wildcard = "Text files (*.txt)|*.txt|All files (*.*)|*.*"
            dlg = wxFileDialog(self, "Save file as...", "", "",
wildcard, wxSAVE)
            if dlg.ShowModal() == wxID_OK:
                path = dlg.GetPath()
            dlg.Destroy() 

            if os.path.exists(path):
                dlg = wxMessageDialog(self, 'Overwrite %s?' % path,
                                      'Confirm overwrite file',
                                      wxYES_NO | wxNO_DEFAULT |
wxICON_QUESTION)
                response = dlg.ShowModal()
                dlg.Destroy()
                if response != wxID_YES:
                    return
            self.path = path
            
        f = file(self.path, 'w')
        f.write(text)
        f.close()
        
                        
class App(wxApp):
    def OnInit(self):
        frame = main_window(None, -1, "wxPython: (A Demonstration)")
        frame.Show(true)
        self.SetTopWindow(frame)
        return true

app = App(0)
app.MainLoop()
