discovery: prevent deleting items from a dictionary

Removing elements from Python dictionary is expensive. So let's prevent adding
them instead.

I added a newline to make code look a bit better.

from __future__ import absolute_import, print_function

import errno
import os
import sys

for f in sys.argv[1:]:
    try:
        print(f, '->', os.readlink(f))
    except OSError as err:
        if err.errno != errno.EINVAL:
            raise
        print(f, '->', f, 'not a symlink')

sys.exit(0)
