Ah, the old adage "If it compiles it's done" ;)

I'm not completely sure what you are expecting. If you want to print

file somefile.jpg not a duplicate 

for files not in the target_directory_file_list you need another else for 
the outer if

         else:
             print("file", current_filename, 
                   "not a duplicate (different size)")
     else:
         print("file ", current_filename, 
               "not a duplicate (not in target directory)")
