The lines that shall be executed when world_is_flat is True must be indented 
more than the if. If you don't follow this rule Python complains and raises 
an IndentationError. 

>>> if world_is_flat:
... print "be careful"
  File "<stdin>", line 2
    print "be careful"
        ^
IndentationError: expected an indented block

The easiest way to indent in interactive mode is to hit TAB once:

>>> if world_is_flat:
...     print "be careful"
...
be careful

By the way, you should not retype your error messages because that is error 
prone. Instead cut and paste. I think there is an entry in the system menu 
of the dos window to help you do that.
