我正在嘗試通過boto3和python3腳本從Amazon ec2的s3存儲桶中下載所有示例文件到本地硬盤。這是腳本。#downloading files from s3import boto3import sysimport osimport argparseimport threadingfrom botocore.client import Configinstance_id = "i-03e7f6391a0f523ee"action = 'ON'ec2 = boto3.client('ec2')s3=boto3.resource('s3')for bucket in s3.buckets.all():    print(bucket.name)my_bucket=s3.Bucket('tkbucket32')print("listing all files in bucket")for s3_file in my_bucket.objects.all():    print(s3_file.key)s3.meta.client.download_file('tkbucket32', 'hello.txt', '/tmp/hello.txt')當前存儲桶中有以下文件你好.txt myhomepage.html現在我希望它們被下載到D:\folder1\folder2\folder3我在 Windows 7 中運行腳本。我的問題是這一行s3.meta.client.download_file('tkbucket32', 'hello.txt', '/tmp/hello.txt')我在哪里指定要下載這些文件的本地硬盤驅動器的路徑？
