尝试使用python获取dynamodb中某列中所有属性的列表

pip install boto3

import boto3
from botocore.exceptions import NoCredentialsError

dynamodb = boto3.client('dynamodb')

table_name = 'your_table_name'
column_name = 'your_column_name'

try:
    response = dynamodb.scan(
        TableName=table_name,
        ProjectionExpression=column_name
    )
    items = response['Items']
    while 'LastEvaluatedKey' in response:
        response = dynamodb.scan(
            TableName=table_name,
            ProjectionExpression=column_name,
            ExclusiveStartKey=response['LastEvaluatedKey']
        )
        items.extend(response['Items'])
except NoCredentialsError:
    print("无法找到AWS凭证")

attribute_values = [item[column_name]['S'] for item in items]
