You can delete objects when they are no longer needed to reduce costs. The current TOS Python SDK supports deleting a single object in a bucket and deleting multiple specified objects. For buckets with versioning enabled, you can delete any version of an object by specifying its version ID.
Notes
- When deleting objects, you must have the tos:DeleteObject permission. For details, see the Permission Configuration Guide.
- When deleting versioned objects, you must have the tos:DeleteObjectVersion permission. For details, see the Permission Configuration Guide.
- When a bucket’s versioning status is enabled, deleting an object without specifying a version ID will not delete the object but will generate a new version with a deletion marker (DeleteMarker). When the bucket’s versioning status is Suspended, deleting the versioned objectnulland generating a deletion marker with version IDnullwill occur. In a versioning-enabled bucket, specifying a version ID while deleting an object deletes that particular version.
Sample code
Delete specified object
The following code deletes the obejct-test object in the specified bucket bucket-test.
import os
import tos
# Retrieve AKSK information from environment variables.
ak = os.getenv('TOS_ACCESS_KEY')
sk = os.getenv('TOS_SECRET_KEY')
endpoint = "your endpoint"
region = "your region"
bucket_name = 'bucket-test'
object_key = 'object-key'
try:
# Create a TosClientV2 object to perform operations on buckets and objects
client = tos.TosClientV2(ak, sk, endpoint, region)
# Delete specified objects under a specified bucket.
resp = client.delete_object(bucket_name, object_key)
except tos.exceptions.TosClientError as e:
# Operation failed, catch client error, usually caused by invalid request parameters or network issues
print('fail with client error, message:{}, cause: {}'.format(e.message, e.cause))
except tos.exceptions.TosServerError as e:
# Operation failed, catch server error, detailed error information can be obtained from the response
print('fail with server error, code: {}'.format(e.code))
# request id can be used to locate specific issues, it is strongly recommended to save it in the log.
print('error with request id: {}'.format(e.request_id))
print('error with message: {}'.format(e.message))
print('error with http code: {}'.format(e.status_code))
print('error with ec: {}'.format(e.ec))
print('error with request url: {}'.format(e.request_url))
except Exception as e:
print('fail with unknown error: {}'.format(e))
Delete specified version object
The following code deletes a specified version of the obejct-test object in the version-enabled bucket bucket-test.
import os
import tos
# Retrieve AKSK information from environment variables.
ak = os.getenv('TOS_ACCESS_KEY')
sk = os.getenv('TOS_SECRET_KEY')
endpoint = "your endpoint"
region = "your region"
bucket_name = 'bucket-test'
object_key = 'object-key'
version_id = "your object version"
try:
# Create a TosClientV2 object to perform operations on buckets and objects
client = tos.TosClientV2(ak, sk, endpoint, region)
# Delete specified objects under a specified bucket.
client.delete_object(bucket_name, object_key, version_id=version_id)
except tos.exceptions.TosClientError as e:
# Operation failed, catch client error, usually caused by invalid request parameters or network issues
print('fail with client error, message:{}, cause: {}'.format(e.message, e.cause))
except tos.exceptions.TosServerError as e:
# Operation failed, catch server error, detailed error information can be obtained from the response
print('fail with server error, code: {}'.format(e.code))
# request id can be used to locate specific issues, it is strongly recommended to save it in the log.
print('error with request id: {}'.format(e.request_id))
print('error with message: {}'.format(e.message))
print('error with http code: {}'.format(e.status_code))
print('error with ec: {}'.format(e.ec))
print('error with request url: {}'.format(e.request_url))
except Exception as e:
print('fail with unknown error: {}'.format(e))
Batch delete objects
tip
- In a version-controlled bucket, when calling the DeleteMultiObjects API to batch delete objects, if the versionId is not specified in the Delete request, a delete marker will be inserted. If the versionId is specified, the specified version of the object will be permanently deleted.
- The response mode supported by batch deleting objects can be set via quiet:
- When quiet is false, all deletion results will be included in the response regardless of whether the objects are deleted successfully.
- When quiet is true, only the failed deletion results are returned in the response; no returned results indicate successful deletion.
The following code deletes multiple objects with the specified object name from the bucket bucket-test.
import os
import tos
from tos.models2 import ObjectTobeDeleted
# Retrieve AKSK information from environment variables.
ak = os.getenv('TOS_ACCESS_KEY')
sk = os.getenv('TOS_SECRET_KEY')
endpoint = "your endpoint"
region = "your region"
bucket_name = 'bucket-test'
object_key_1 = "your object key1"
object_key_2 = "your object key2"
try:
# Create a TosClientV2 object to perform operations on buckets and objects
client = tos.TosClientV2(ak, sk, endpoint, region)
# Batch delete specified objects under a specified bucket
objects = []
objects.append(ObjectToBeDeleted(object_key_1))
objects.append(ObjectToBeDeleted(object_key_2))
# If the bucket has versioning enabled and no object version is specified, it will be a delete marker
# For buckets without versioning enabled, the objects will be directly deleted
delete_out = client.delete_multi_objects(bucket=bucket_name, objects=objects)
# deleted contains the objects that have been successfully deleted.
for deleted in delete_out.deleted:
# Delete object key
print('success deleted object key', deleted.key)
# Delete object version id
print('success delete object version id', deleted.version_id)
# delete_marker indicates if it is a delete marker object
print('is delete marker', deleted.delete_marker)
# delete_marker_version_id is the version ID corresponding to the delete marker
print('delete marker version id', deleted.delete_marker_version_id)
# error contains the object that failed to be deleted.
for err in delete_out.error:
print('delete err key', err.key)
print('delete err key version', err.version_id)
print('delete err message', err.message)
except tos.exceptions.TosClientError as e:
# Operation failed, catch client error, usually caused by invalid request parameters or network issues
print('fail with client error, message:{}, cause: {}'.format(e.message, e.cause))
except tos.exceptions.TosServerError as e:
# Operation failed, catch server error, detailed error information can be obtained from the response
print('fail with server error, code: {}'.format(e.code))

object_key_1 = "your object key1"
version_id_1 = "your object_key_1 version id"
object_key_2 = "your object key2"
version_id_2 = "your object_key_2 version id"
try:
# Create a TosClientV2 object to perform operations on buckets and objects
client = tos.TosClientV2(ak, sk, endpoint, region)
# Delete specified objects under specified bucket in batch.
objects = []
objects.append(ObjectTobeDeleted(object_key_1, version_id_1))
objects.append(ObjectTobeDeleted(object_key_2, version_id_2))
# If the bucket is enabled with versioning and a specific version number is specified for deleting an object, it is directly marked for deletion.
delete_out = client.delete_multi_objects(bucket=bucket_name, objects=objects)
# deleted contains the objects that have been successfully deleted.
for deleted in delete_out.deleted:
# Delete object key
print('success deleted object key', deleted.key)
# Delete object version id
print('success delete object version id', deleted.version_id)
# is_delete_marker indicates if the object is a delete marker
print('is delete marker', deleted.delete_marker)
# delete_marker_version_id is the version ID corresponding to the delete marker
print('delete marker version id', deleted.delete_marker_version_id)
# error contains the object that failed to be deleted.
for err in delete_out.error:
print('delete err key', err.key)
print('delete err key version', err.version_id)
print('delete err message', err.message)
