IndentationError: unexpected indent

[desktop]

I have this class:

class case(blop.case):
   def __init__(self, n, a, b):
     blop.case.__init__(self)
     print 'Monty Python's Flying Circus has a ' within it...'
     ...
     ...

But I get an error when I run the .py script from shell saying:

     print 'Monty Python's Flying Circus has a ' within it...'
     ^
IndentationError: unexpected indent

I have tried to indent the print statement 8 blanks but that does not 
help. Any hints?
