LTFigure
Represents an area used by PDF Form objects. PDF Forms can be used to present figures or pictures by embedding yet another PDF document within a page. Note that LTFigure objects can appear recursively.
two_dict = {4:{'key':'test_1', 'key_2':'test_21'}, 5:{'key':'test_11', 'key_2':'test_22'}}
result = [two_dict[x] for x in two_dict if two_dict[x]['key'] == 'test_1']
