如何在使用Python的dynamodb中使用in运算符

import boto3
from boto3.dynamodb.conditions import Key

dynamodb = boto3.client('dynamodb')

table_name = 'your_table_name'
filter_expression = 'attribute_name IN (:val1, :val2, ...)'
expression_attribute_values = {
    ':val1': {'S': 'value1'},
    ':val2': {'S': 'value2'},
    ...
}

response = dynamodb.scan(
    TableName=table_name,
    FilterExpression=filter_expression,
    ExpressionAttributeValues=expression_attribute_values
)

items = response['Items']
for item in items:
    # 处理每个符合条件的项
    print(item)
