General help with hide show toolbar for a begineer in python

[ArakelTheDragon]

Hi guys!
I have the following code, everything is working, except that I can't get the function for hiding the tool bar to work. Originally I was using a different approach from a tutorial, it was working, but now that I added new things and changed some old, I get a problem.

error: AttributeError: 'Example' object has no attribute 'toolbar'
 

I tried changing the function "toolbar.Hide()" with "toolbar = toolbar.Hide()" and "toolbar = Hide()" and a few other things, but it does not work. Can someone explain to me the difference between the 2 approaches and how to fix the problem?

Also a good python function reference would be good.

Thanks in advance!

Important part of the code, new appraoch:

                                    #Toolbar block.
toolbar = self.CreateToolBar()#Visual creation of the toolbar.
QuitTool = toolbar.AddTool(wx.ID_ANY, 'Exit', wx.Bitmap('exit.png'))#Adding picture to the toolbar button.
OpenTool = toolbar.AddTool(wx.ID_ANY, 'Open', wx.Bitmap('o.png'))#Adding picture to the toolbar button.
toolbar.Realize()
 
self.Bind(wx.EVT_TOOL, self.OnQuit, QuitTool)#Adding operation to the toolbar button.
self.Bind(wx.EVT_TOOL, self.OnQuit, OpenTool)#Adding operation to the toolbar button.
..........................
def ToggleToolBar(self, e):#Function for the menu function block. Different toolbar. For ticking on/of the toolbar.
if self.shtl.IsChecked():
    toolbar.Show()
else:
    toolbar.Hide() 
 

Important part of the code old approach.

self.toolbar = self.CreateToolBar()#Visual creation of the toolbar.
self.toolbar.AddTool(1, '', wx.Bitmap('exit.png'))#Adding picture to the toolbar button.
self.toolbar.Realize()#Adding operation to the toolbar button.
.........................
def ToggleToolBar(self, e):#Function for the menu function block.
if self.shtl.IsChecked():
    self.toolbar.Show()
else:
    self.toolbar.Hide()
