Ah ok. I assumed you were only interested catching exceptions rather than the 
exception itself, since you were using a blanket except statement.

yeah, yeah :) ...that was just pseudo code to emphasize the fact that the object 
is available. In any case, if you really want to be pedantic, you ought to be 
raising custom exceptions rather than the base Exception object and also 
catching specific exceptions rather than a blanket except !
