I presume this is due to tokenization or something, but there's a lot of extra whitespace in the code samples that make them look very unrealistic:

  def _ _ init__(self, default): 
  " " " 
  See if the default value for the field on a view is 
  timespan. 
  " " " 

  < select > 
  < option > value < / option > 
  < option > value < / option > 
  < / select >

And indentation is also missing completely. Maybe you need to use another NN to guess which language the fake code is in and autoformat it accordingly!
