Hmm,
I opened it up in EditPad Lite but I see no line numbers.

Here is the first block without the annotations:

from Tkinter import *
import poser,string

scene = poser.Scene()

class App:
  def init(self, master):
    self.MainButtonWidth = 9
    self.FullActorList = []
    self.DeformerList = []
    self.MagnetList = []
    self.MagnetPairsList = []
    self.FigureSelected = 'no'
    self.FromQuit = 'no'
    self.CloneDone = 'no'
    self.FullParameterList1 = []
    self.Frame4ButtonWidth = 3
    self.Mode = 0
    self.SaveCurrentFigureName = ''
    self.InactiveMags = []
    self.ActiveMags = []
    self.InactiveMagNames = []
    self.ActiveMagNames = []
    self.ReselectMags = 'yes'
    self.UndoDictionary =
    self.UndoCount = 0
    self.MagnetDictionary =
    self.MagnetCount = 0
    self.DummyFont = ('Arial','1')
