[Tutor] Fwd: thesaurus

[Pete Froslie]

Great Richard, thanks..

I'm getting an error as follows:

from __future__ import with_statement
SyntaxError: from __future__ imports must occur at the beginning of the file

I don't think this is the issue in need of rework and have tried a few quick
reworks.. I'll read up a bit on 'with'

cheers
