see my added comment in the code above...

Though this will produce spaces between the dots:

   waiting . . . . . .

To eliminate the spaces, you need to write to a file-stream such 
as sys.stdout:

   from sys import stdout
   stdout.write('working')
   while True:
     stdout.write('.')
     # might need something like stdout.flush() here
     time.sleep(1)
   stdout.write('\n')
