These look like you're indexing objects Key, Key2, Key3 by
dictionaries, or possibly these are the result of printing dict-like
objects with custom __repr__() methods. Could you give more
information about what's actually going on here?

"Searching" a dict is accomplished by simply asking for the key: d['item1']
I'm going to guess you meant something like this:
list_of_dicts = [Key, Key2, Key3]
new_dict = {}
for i, k in enumerate(list_of_dicts):
 value = k['item1']
 if value == some_specific_value:
 new_dict[i] = value
But it's not really clear from your post exactly what you meant to ask.
