如何从零开始使用S3向新创建的boto3桶添加标记(最初还没有标记)？

Question

我想将标记添加到s3桶、新创建的和使用pythonboto3的现有存储桶中。

import boto3
from botocore.exceptions import ClientError


s3bucket=boto3.client("s3")
s3=boto3.resource('s3')
falcon_s3=False



print ("=================Adding tags to S3 Buckets==================")
list_bucket=s3bucket.list_buckets()


for buckets in list_bucket['Buckets']:

    try:
    
        Bucket_Existing_tags = s3.BucketTagging(buckets['Name']).tag_set
    
        for tags in Bucket_Existing_tags:
            if tags["Key"]=="Falcon Managed" and tags["Value"] =="true":
                print("This Bucket is belonged to Falcons -->"+ buckets["Name"])
                falcon_s3=True
                break
        else:
                bucket_tagging = s3.BucketTagging(buckets['Name'])
                tags = bucket_tagging.tag_set
                tags.append({'Key':'Technical:Patcher', 'Value': 'goats'})
                Set_Tag = bucket_tagging.put(Tagging={'TagSet':tags})
                print('Tags added for ---> ' + buckets['Name'])


    except ClientError as e:
         print("Unexpected error: %s" % e)

为此，我创建了这个脚本，它正在检查已经有标记的存储桶，并在其中检查是否管理了falocon。如果不是，它会放置另一个标记集。当重新运行该方法时，由于多次不允许添加相同的标记而无法工作(但这应该是可能的，因为我们使用其他资源)。但是这个脚本不适合最初没有标记的s3桶(新创建的标签)。

因此，我需要添加标签到所有的桶在这个特定的帐户(包括新的没有标签)，如果它是猎鹰管理，它不需要添加任何标签。但是，如果不对falcon进行管理，则必须添加新的标记(而不删除现有的标记)。为此，我如何修改此代码？

当没有标记时，我捕获抛出的NoSuchTagSet错误，从而使它正常工作。然后使用默认值创建TagSet。

import boto3
from botocore.exceptions import ClientError

s3bucket = boto3.client("s3")
s3 = boto3.resource('s3')
falcon_s3 = False

print("=================Adding tags to S3 Buckets==================")
list_bucket = s3bucket.list_buckets()

for bucket in list_bucket:
    try:
        existing_bucket_tagging = s3.BucketTagging(bucket).tag_set

        for tags in existing_bucket_tagging:
            if tags["Key"] == "Falcon Managed" and tags["Value"] == "true":
                print("This Bucket is belonged to Falcons -->" + bucket)
                falcon_s3 = True
                break

    except ClientError as e:
        if e.response['Error']['Code'] == 'NoSuchTagSet':
            print(bucket + ",does not have tags, adding tag")

            bucket_tagging = s3.BucketTagging(bucket)

            bucket_tagging.put(
                Tagging={
                    'TagSet': [
                        {
                            'Key': 'Technical:Patcher',
                            'Value': 'goats'
                        },
                    ]
                }
            )
            print('Tags added for ---> ' + bucket)
        else:
            print("Unexpected error: %s" % e)
