input: Write a python function to search for values in a dictionary given a list of keys.
  assert search_dictionary({'a': 1, 'b': 2, 'c': 3}, ['a', 'c']) == [1, 3]
  assert search_dictionary({'x': 10, 'y': 20, 'z': 30}, ['y']) == [20]
  assert search_dictionary({'m': 5, 'n': 6, 'o': 7}, ['m', 'n', 'o']) == [5, 6, 7]
output: def search_dictionary(d, keys):
      return [d[key] for key in keys if key in d]
