如何在删除每个字典的子集时合并成对的字典

def merge_dicts(dicts):
    result = {}
    for current_dict in dicts:
        merged = False
        for key, value in current_dict.items():
            for other_dict in dicts:
                if other_dict is not current_dict and key in other_dict and other_dict[key] == value:
                    merged_dict = {**current_dict, **other_dict}
                    result = merge_dicts([result, merged_dict])
                    merged = True
                    break
            if merged:
                break
        if not merged:
            result = merge_dicts([result, current_dict])
    return result

# 示例用法
dicts = [
    {"a": 1, "b": 2},
    {"b": 2, "c": 3},
    {"d": 4, "e": 5},
    {"f": 6, "g": 7}
]
merged_dict = merge_dicts(dicts)
print(merged_dict)

{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5, 'f': 6, 'g': 7}
