如何在S3 boto3中删除多个文件和特定模式

import boto3
from botocore.exceptions import NoCredentialsError

s3 = boto3.client('s3')

def delete_files(bucket_name, prefix, pattern):
    try:
        response = s3.list_objects_v2(Bucket=bucket_name, Prefix=prefix)
        if 'Contents' in response:
            for obj in response['Contents']:
                key = obj['Key']
                if pattern in key:
                    s3.delete_object(Bucket=bucket_name, Key=key)
        else:
            print("No objects found matching the prefix and pattern.")
    except NoCredentialsError:
        print("Credentials not found.")

bucket_name = 'your_bucket_name'
prefix = 'your_prefix'
pattern = 'your_pattern'

delete_files(bucket_name, prefix, pattern)
