请给我一个实例用python上传设备属性数据到华为云

当然，下面是一个使用Python上传设备属性数据到华为云的示例代码：

import requests
import json

# 设备信息
device_id = "your_device_id"
gateway_id = "your_gateway_id"
product_id = "your_product_id"
access_key = "your_access_key"
access_secret = "your_access_secret"

# API请求地址
url = f"https://iotda.{your_region}.myhuaweicloud.com/v5/iot/{device_id}/services"

# 请求头信息
headers = {
    "Content-Type": "application/json"
}

# 请求体数据
data = {
    "serviceId": "your_service_id",
    "serviceType": "your_service_type",
    "data": {
        "property1": "value1",
        "property2": "value2",
        "property3": "value3"
    }
}

# 将请求体数据转换为JSON字符串
data_json = json.dumps(data)

# 生成签名字符串
sign_str = f"POST\napplication/json\n\n\n\n\n\n\n\n\n\n\nx-iotda-access-key:{access_key}\nx-iotda-service-time:"

# 生成签名
import hmac
import hashlib
import base64

signature = base64.b64encode(
    hmac.new(
        bytes(access_secret, 'utf-8'),
        msg=bytes(sign_str, 'utf-8'),
        digestmod=hashlib.sha256
    ).digest()
).decode('utf-8')

# 构建请求头信息
headers.update({
    "X-Iotda-Access-Key": access_key,
    "X-Iotda-Service-Time": "",
    "Authorization": f"HMAC-SHA256 Access={signature}"
})

# 发送POST请求
response = requests.post(url, headers=headers, data=data_json)

# 打印响应结果
print(response.status_code)
print(response.json())

请注意替换示例代码中的以下信息：
- `your_device_id`：设备ID
- `your_gateway_id`：网关ID
- `your_product_id`：产品ID
- `your_access_key`：Access Key
- `your_access_secret`：Access Secret
- `your_region`：华为云地区（例如，＊＊＊
