Your problem is that the return from the File dialog is a list of file 
names (so that the user can select multiple files for input - don't think 
that applies for a Save dialog - but the result is still a list of file 
names).

so you need to do maybe

   myfile - result['paths'][0]
or even
   myfile = result['paths']
   if len(myfile) > 0:
      myfile = myfile[0]
