BOTO3 :如何过滤标签不等于的实例？

import boto3

# 创建EC2客户端
ec2_client = boto3.client('ec2')

# 定义标签过滤条件
filters = [
    {
        'Name': 'tag:Key',
        'Values': ['Value'],
        'Name': 'tag:Key2',
        'Values': ['Value2'],
        'Name': 'tag:Key3',
        'Values': ['Value3']
    },
    {
        'Name': 'tag:Key4',
        'Values': ['Value4']
    }
]

# 获取符合过滤条件的实例
response = ec2_client.describe_instances(Filters=filters)

# 处理返回结果
for reservation in response['Reservations']:
    for instance in reservation['Instances']:
        # 处理每个实例
        instance_id = instance['InstanceId']
        # 其他操作...
