Introduction to Python SDK

This article introduces the usage methods, interface definitions, and parameter explanations of the Volcano Engine Torch Object Storage Python SDK in various scenarios.

Explanation.

Precautions

In multi-process scenarios, create multiple TosClients instead of sharing one TosClient to avoid concurrency issues that may cause data to be corrupted during read and write requests.

Example code

The SDK provides example code for bucket and object operations for your reference.
