根据标签名称过滤实例，并在Python中打印特定的标签值

# 导入腾讯云SDK
from qcloud_sdk import QcloudApi

# 实例化API对象
module = 'cvm'
action = 'DescribeInstances'
config = {
    'Region': 'ap-guangzhou',  # 地域，根据实际情况填写
    'secretId': 'your_secret_id',  # 替换为你的腾讯云API密钥ID
    'secretKey': 'your_secret_key',  # 替换为你的腾讯云API密钥Key
    'method': 'GET',
    'SignatureMethod': 'HmacSHA1'
}
service = QcloudApi(module, config)

# 设置过滤条件
filters = {
    'tag-key': 'your_tag_key',  # 替换为你要过滤的标签键
    'tag-value': 'your_tag_value'  # 替换为你要过滤的标签值
}

# 调用API查询实例列表
params = {
    'Filters': filters
}
result = service.call(action, params)

# 解析返回结果并打印特定标签的值
instances = result['Response']['InstanceSet']
for instance in instances:
    tags = instance['Tags']
    for tag in tags:
        if tag['Key'] == 'your_tag_key':  # 替换为你要打印的标签键
            print(tag['Value'])  # 打印标签值
