The other answers delete objects individually. It is more efficient to use the delete_objects boto3 call and batch process your delete. See the code below for a function which collects all objects and deletes in batches of 1000:

bucket = 'bucket-name'
s3_client = boto3.client('s3')
object_response_paginator = s3_client.get_paginator('list_object_versions')

delete_marker_list = []
version_list = []

for object_response_itr in object_response_paginator.paginate(Bucket=bucket):
    if 'DeleteMarkers' in object_response_itr:
        for delete_marker in object_response_itr['DeleteMarkers']:
            delete_marker_list.append({'Key': delete_marker['Key'], 'VersionId': delete_marker['VersionId']})

    if 'Versions' in object_response_itr:
        for version in object_response_itr['Versions']:
            version_list.append({'Key': version['Key'], 'VersionId': version['VersionId']})

for i in range(0, len(delete_marker_list), 1000):
    response = s3_client.delete_objects(
        Bucket=bucket,
        Delete={
            'Objects': delete_marker_list[i:i+1000],
            'Quiet': True
        }
    )
    print(response)

for i in range(0, len(version_list), 1000):
    response = s3_client.delete_objects(
        Bucket=bucket,
        Delete={
            'Objects': version_list[i:i+1000],
            'Quiet': True
        }
    )
    print(response)
