Hi.

I am having a problem in creating of one simple program in Python.
Here is code.

import wx

class bucky(wx.Frame):
  def __init__(self, parent, id):
    wx.Frame.__init__(self, parent, id, "Testing erea", size=(280,400))

    panel = wx.Panel(self)
    food = wx.Button(panel,label='Food',pos=(10,10),size=(80,40))
    pets = wx.Button(panel, label='Pets', pos=(100,10), size=(80,40))
    
    self.Bind(wx.EVT_BUTTON, self.food, food
              )
  def food(self, event):
    wx.StaticText(parent, -1, 'Bacon, apples, tuna', (10,30))

    self.Bind(wx.EVT_CLOSE,self.closewindow)
  def closewindow(self,event):
    self.Destroy()
    
if __name__=='__main__':
  app=wx.PySimpleApp()
  frame=bucky(parent=None,id=-1)
  frame.Show()
  app.MainLoop()

1.What my program does is it has two buttons: "Food" and "Pets".
When I click "Food" button I want line of a text on a screen to appear.
("Pets" button does not do nothing yet).

2.The result of my program. I get two buttons on a screen,
but when I click "Food" button the error message in "Python Shell" window appears.
It says "NameError: global name 'parent' is not defined".

3.I want text on a screen to change depends on what button I clicked.
When I click on "Food" I want list of food to appear.
When I click on "Pets" I want list of my pets to appear.

Thank you for help. I am hopping to understand the concept,
so I can add more complex stuff instead of just printing lines out.
Thank you again, whoever will respond.
