[Tutor] Odd AttributeError

[Lloyd Kvam]

The secret could be in the lines you left out.  file is not a good
variable name since it is also a python type.  Your code works:
(i changed file to filex)

class ID3:
      def __init__(self, filex, name='unknown filename', as_tuple=0):
          print 'printing as_tuple:', as_tuple
          print 'defining self.as_tuple . . .'
          self.as_tuple = as_tuple
          print 'printing self.as_tuple: ', self.as_tuple

filex = file(r'c:\autoexec.bat','rt')
ID3(filex)

  >>> printing as_tuple: 0
defining self.as_tuple . . .
printing self.as_tuple:  0
