# aliyun-python-sdk-core — The core module of Aliyun Python SDK.

License: permissive · Maintenance: active · Downloads: 7.2M/mo

## What it is and what it does

aliyun-python-sdk-core is the foundational client library for the Alibaba Cloud Python SDK V1.0. It handles the low-level mechanics of communicating with Alibaba Cloud APIs: creating authenticated client instances, formatting and sending requests, parsing responses, and managing exceptions. The package requires Python 3.7 or later and supports current Python versions through 3.12.

The package is now in basic security maintenance mode and no longer receives new features. The maintainers strongly recommend using V2.0 SDK for new projects, citing better performance, a more concise API, and more complete documentation. Existing V1.0 deployments can continue to use this package, but migration to V2.0 is advised.

Use it for:

- Maintain legacy Alibaba Cloud integrations written against the V1.0 SDK without immediate rewrite
- Call Alibaba Cloud product APIs from Python when V2.0 is not yet available in your environment
- Prototype or test Alibaba Cloud API calls using the core client before committing to a full SDK upgrade

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides core client infrastructure for calling Alibaba Cloud APIs from Python, handling authentication, request formatting, and response parsing.

No for new projects—use V2.0 SDK instead. Yes-with-conditions for existing V1.0 deployments: install only if you are maintaining legacy code and cannot yet migrate. The package is stable and receives security maintenance, but the maintainers explicitly recommend against starting new work with V1.0.

## Install

pip install aliyun-python-sdk-core
uv add aliyun-python-sdk-core
poetry add aliyun-python-sdk-core

## Installing aliyun-python-sdk-core

Before you install: High install friction due to a single large tarball dependency. The package is actively maintained with recent commits, but the maintainers explicitly recommend migrating to V2.0 SDK for new projects; V1.0 is in basic security maintenance only with no new features planned.

License in practice: Licensed under Apache License 2.0 (permissive), allowing commercial use, modification, and distribution with minimal restrictions.

Quickstart:

pip install aliyun-python-sdk-core

# See documentation for client initialization and API request patterns

Requires Alibaba Cloud Access Key ID and Secret from the Alibaba Cloud console; the product API you intend to call must be activated in your Alibaba Cloud account.

Verify before relying:

- Whether V1.0 receives security patches or only critical fixes during basic maintenance phase
- Performance or API compatibility differences between V1.0 and V2.0 for existing deployments
- Specific module names and import paths available in this package
