You don't. Provided the "handle any other error" part reraises or does a 
break/continue, so as to skip the bottom of the loop body.

     ok = true
     for dirname in listofdirs:
         try:
             os.mkdir(dirname)
         except FileExistsError:
             pass
         except Exception as e:
             warning("mkdir(%r): %s", dirname, e)
             ok = False
             continue
         rest of the loop body ...
     if not ok:
         ... not all directories made ...

2 notes on the above:
- catching Exception, not a bare except (which catches a rather broader 
   suit of things)
- reporting the other exception
