如何从键值对中对相似值进行分组

def group_similar_values(key_value_pairs):
    groups = {}  # 存储分组结果的字典

    for key, value in key_value_pairs:
        # 计算相似值，这里使用字符串长度作为示例
        similarity = len(value)

        # 根据相似值将键值对放入对应的分组中
        if similarity in groups:
            groups[similarity].append((key, value))
        else:
            groups[similarity] = [(key, value)]

    return groups

# 示例数据
key_value_pairs = [
    ('key1', 'value1'),
    ('key2', 'value2'),
    ('key3', 'value3'),
    ('key4', 'value4'),
    ('key5', 'value5'),
    ('key6', 'value6'),
]

# 对相似值进行分组
result = group_similar_values(key_value_pairs)

# 打印分组结果
for similarity, group in result.items():
    print(f"相似值为 {similarity} 的分组：")
    for key, value in group:
        print(f"键：{key}，值：{value}")
    print()
