Object Storage Service:Configure and manage bucket tagging using OSS SDK for Python 2.0

The following sample code configures tags for a bucket:

import argparse
import alibabacloud_oss_v2 as oss

# Create a command-line parameter parser for parsing parameters from the command line.
parser = argparse.ArgumentParser(description="put bucket tags sample")

# (Required) Specify the region parameter, which specifies the region in which the bucket is located. 
parser.add_argument('--region', help='The region in which the bucket is located.', required=True)

# (Required) Specify the --bucket parameter, which specifies the name of the bucket.
parser.add_argument('--bucket', help='The name of the bucket.', required=True)

# (Optional) Specify the --endpoint parameter, which specifies the endpoint that other services can use to access OSS.
parser.add_argument('--endpoint', help='The domain names that other services can use to access OSS')

def main():
    # Parse the command-line parameters.
    args = parser.parse_args()

    # Load access credentials (AccessKey ID and AccessKey secret) from environment variables.
    credentials_provider = oss.credentials.EnvironmentVariableCredentialsProvider()

    # Load the default configurations of the SDK.
    cfg = oss.config.load_default()

    # Specify the credential provider.
    cfg.credentials_provider = credentials_provider

    # Specify the region in which the bucket is located.

    # If a custom endpoint is provided, update the endpoint attribute with the provided endpoint.
    if args.endpoint is not None:
        cfg.endpoint = args.endpoint

    # Use the preceding configurations to initialize the OSSClient instance.
    client = oss.Client(cfg)

    # Call the put_bucket_tags method to configure tags for the bucket.
    result = client.put_bucket_tags(
        oss.PutBucketTagsRequest(

                    ],

            ),
        )
    )
