如何使用python在亚马逊s3存储桶中获取csv文件名？

pip install boto3

import os

os.environ["AWS_ACCESS_KEY_ID"] = "Your_AWS_Access_Key_ID"
os.environ["AWS_SECRET_ACCESS_KEY"] = "Your_AWS_Secret_Access_Key"
os.environ["AWS_DEFAULT_REGION"] = "Your_AWS_Region"

import boto3

def get_csv_filenames(bucket_name):
    s3 = boto3.client('s3')
    response = s3.list_objects_v2(Bucket=bucket_name)
    
    csv_filenames = []
    for obj in response['Contents']:
        key = obj['Key']
        if key.endswith('.csv'):
            csv_filenames.append(key)
    
    return csv_filenames

bucket_name = "your_bucket_name"
csv_files = get_csv_filenames(bucket_name)
for file in csv_files:
    print(file)
