Python function to create a list of unuque dicts
def unique_items(keys, objects):
# Extract relevant items based on keys and create frozensets for uniqueness
items = [{key: obj[key] for key in keys if key in obj} for obj in objects]
# Use frozenset to ensure uniqueness
set_of_dicts = {frozenset(d.items()) for d in items}
# Convert back to dictionaries for easier usability
unique_dicts = [dict(s) for s in set_of_dicts]
print(len(unique_dicts))
return unique_dicts
