python - How to use multiple wxPython project files in one program? -

i trying make pretty big app many different parts , windows. decided lot cleaner if had windows have own file , import them main file. tried when try run class, gives error of needing 3 arguments. not understand how should go doing appreciated! main file:

import wx import login login.apples(self,parent,id) class oranges(wx.frame):     def __init__(self,parent, id):         wx.frame.__init__(self,parent,id,"mail",size=(700,700))         self.frame=wx.panel(self) if __name__=="__main__":     app=wx.app(false)     window=oranges(parent=none, id=-1)     window.show()     app.mainloop() 

i nameerror: name "self" not defined.

import wx class apples(wx.frame):     def __init__(self,parent,id):         wx.frame.__init__(self,parent,id,"login mail",size=(400,400))         self.frame=wx.frame(self)    if __name__=="__main__":     app=wx.app(false)     window=apples(parent=none, id=-1)     window.show()     app.mainloop() 

import wx import login #login.apples(self,parent,id) #this line wont work ... there no self here... #see below in if __name__ == "__main__" part class oranges(wx.frame):     def __init__(self,parent, id):         wx.frame.__init__(self,parent,id,"mail",size=(700,700))         self.frame=wx.panel(self) if __name__=="__main__":     app=wx.app(false)      window=oranges(parent=none, id=-1)     other_window = login.apples(parent=none,id=-1)     window.show()     other_window.show()     app.mainloop()
