There wouldn't be anything to stop you.  However, if you have multiple 
returns from the same function, it's usually wise to return the same 
type of information from each of them.  That's why Chris suggested 
simply assigning to filename in the if clause.

But without the whole function, and maybe even a description of what the 
function is expected to do, we can only guess.

Your comments still make no sense to me,

 > filename = input('file name: ')
 > if not filename:      #i get filename is not defined

But filename IS defined, immediately above. If it were undefined, you'd 
not be able to test it here.  Big difference between "not defined" and 
"is empty string".

from user?

If drawBoard is a function object, it's certainly possible to return it. 
  But again, without seeing the rest of the function, and maybe how it's 
intended to be used, I can't confirm whether it makes sense.
