Python uses indentation to delimit blocks, for example an if statement 
will be followed by an indented block:

if a < b:
   print 'a is less than b'

One way you can get this error is if you mix tabs and spaces for the 
indent character. Common usage is to use four spaces for an indent. 
Check that your code is consistent in its use of tabs or spaces.

It's also possible that you are just missing a character or two.

Posting actual code and the full error message including the traceback 
might help, though whitespace problems might be hidden in email.
