如何从一个S3文件向dynamodb python3.8读写多个json对象

import boto3

dynamodb = boto3.client('dynamodb', aws_access_key_id='YOUR_ACCESS_KEY',
                        aws_secret_access_key='YOUR_SECRET_KEY',
                        region_name='YOUR_REGION')

s3 = boto3.client('s3', aws_access_key_id='YOUR_ACCESS_KEY',
                  aws_secret_access_key='YOUR_SECRET_KEY',
                  region_name='YOUR_REGION')

bucket_name = 'YOUR_BUCKET_NAME'
file_name = 'YOUR_FILE_NAME.json'

s3.download_file(bucket_name, file_name, '/tmp/' + file_name)  # 下载到本地/tmp目录下

with open('/tmp/' + file_name, 'r') as file:
    json_data = file.readlines()

table_name = 'YOUR_DYNAMODB_TABLE_NAME'

for line in json_data:
    json_object = json.loads(line)
    response = dynamodb.put_item(
        TableName=table_name,
        Item=json_object
    )
    print(response)  # 打印写入结果
