Alibaba Cloud SDK for Python
Alibaba Cloud Python Software Development Kit
中文文档
The Alibaba Cloud Python Software Development Kit (SDK) allows you to access Alibaba Cloud services such as Elastic Compute Service (ECS), Object Storage Service (OSS), and Resource Access Management (RAM). You can access Alibaba Cloud services without the need to handle API related tasks, such as signing and constructing your requests.
This document introduces how to obtain and call Alibaba Cloud Python SDK.
Troubleshoot
Troubleshoot Provide OpenAPI diagnosis service to help developers locate quickly and provide solutions for developers through RequestID
or error message
.
Online Demo
API Workbench provides the ability to call the cloud product OpenAPI online, and dynamically generate SDK Example code and quick retrieval interface, which can significantly reduce the difficulty of using the cloud API. It is highly recommended.

Prerequisites
-
To use Alibaba Cloud Python SDK, you must have an Alibaba Cloud account as well as an AccessKey.
The AccessKey is required when initializing
AcsClient
. You can create an AccessKey in the Alibaba Cloud console. For more information, see Create an AccessKey.Note: To increase the security of your account, we recommend that you use the AccessKey of the RAM user to access Alibaba Cloud services.
-
To use Alibaba Cloud Python SDK to access the APIs of a product, you must first activate the product on the Alibaba Cloud console if required.
-
Alibaba Cloud Python SDK requires 2.7.x, and Python 3.x.
Install Python SDK
Alibaba Cloud Python SDK supports Python 2.7.x, and Python 3.x. Run python --version
to check your version of Python.
You can install the Alibaba Cloud Python SDK using the following two methods. Regardless of which method and cloud service are used, the core library aliyun-python-sdk-core
must be installed.
-
Install with pip
Python SDK uses a common package management tool named
pip
. If pip is not installed, see the pip user guide to install pip.Run the following command to install the individual libraries of Alibaba Cloud services:
Install the core library ip install aliyun-python-sdk-core Install the ECS management library ip install aliyun-python-sdk-ecs Install the RDS management library ip install aliyun-python-sdk-rds
Use Python SDK
-
Import the required modules as follows:
from aliyunsdkcore.client import AcsClient from aliyunsdkcore.acs_exception.exceptions import ClientException from aliyunsdkcore.acs_exception.exceptions import ServerException from aliyunsdkecs.request.v20140526 import DescribeInstancesRequest from aliyunsdkecs.request.v20140526 import StopInstanceRequest
-
Initialize the
AcsClient
instance:client = AcsClient( "<access-key-id>", "<access-key-secret>", "<region-id>" )
where:
-
access-key-id
is the Accesskey ID for your account. -
access-key-secret
is the AccessKey secret for your account. -
region-id
is the ID of the region where the service is called. For a list of region IDs, see Regions and zones.
Note: The sequence of these parameters cannot be changed.
-
-
Initialize a request and print response.
# Initialize a request and set parameters request = DescribeInstancesRequest.DescribeInstancesRequest() request.set_PageSize(10) # Print response response = client.do_action_with_exception(request) print response
Code example
The following example shows how to query a list of ECS instances in a specific region using DescribeInstances. Substitute the values for your-access-key-id
, your-access-key-secret
, and your-region-id
.
# -*- coding: utf8 -*-
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkecs.request.v20140526 import DescribeInstancesRequest
from aliyunsdkecs.request.v20140526 import StopInstanceRequest
# Initialize AcsClient instance
client = AcsClient(
"<your-access-key-id>",
"<your-access-key-secret>",
"<your-region-id>"
)
# Initialize a request and set parameters
request = DescribeInstancesRequest.DescribeInstancesRequest()
request.set_PageSize(10)
# Print response
response = client.do_action_with_exception(request)
print response
HTTP DEBUG
To use the function HTTP DEBUG
, you must set DEBUG
in your environment variable, the corresponding value
may be sdk
or SDK
.
The following example shows what the HTTP DEBUG
do, which will help you debug your codes.
