如何在python中使用boto3对象向函数添加类型提示？

pip install boto3-stubs

import boto3
from mypy_boto3_s3 import S3Client
from typing import List

def list_s3_objects(bucket_name: str, s3_client: S3Client) -> List[str]:
    response = s3_client.list_objects_v2(Bucket=bucket_name)
    objects = [obj['Key'] for obj in response.get('Contents', [])]
    return objects

# 创建 S3 客户端
s3_client = boto3.client('s3')

# 调用函数
bucket_name = 'my-bucket'
object_keys = list_s3_objects(bucket_name, s3_client)
print(object_keys)

import boto3
from mypy_boto3_dynamodb.service_resource import DynamoDBServiceResource
from mypy_boto3_dynamodb.service_resource import Table
from typing import Dict, Any

def get_dynamodb_item(table_name: str, key: Dict[str, Any], dynamodb_resource: DynamoDBServiceResource) -> Dict[str, Any]:
    table: Table = dynamodb_resource.Table(table_name)
    response = table.get_item(Key=key)
    return response.get('Item', {})

# 创建 DynamoDB 资源
dynamodb_resource = boto3.resource('dynamodb')

# 调用函数
table_name = 'my-table'
key = {'id': '123'}
item = get_dynamodb_item(table_name, key, dynamodb_resource)
print(item)

pip install mypy

mypy your_script.py
