AttributeError: 'S3' object has no attribute 'Bucket'-CodePudding

What I'm doing wrong?

class S3:
    def __init__(self, b: str, r: str = ""):
        self._bucket = b
        self._remote_dir = r
        self._s3 = client("s3")


def get_bootcamp_dumps(self, file_name):
try:
    my_bucket = self._s3.Bucket(self._bucket)
    dumps_list = []

    for object in my_bucket.objects.all():
        dumps_list.append(object.key)
    filtered_list = [i for i in dumps_list if i.startswith(file_name)]
    return filtered_list
except ClientError as error:
    print(error)

and this is how I'm calling it

s3 = S3(b='my_bucket_name')

dump_list=s3.get_bootcamp_dumps('key_word')

and I'm getting this error

AttributeError: 'S3' object has no attribute 'Bucket'

CodePudding user response：

boto3 has two different ways to access Amazon S3. It appears that you are mixing usage between the two of them.

Client Method

Using a client maps 1:1 with an AWS API call. For example:

import boto3

s3_client = boto3.client('s3')

objects = s3_client.list_objects('bucket-name')

for object in objects['Contents']:
  print(object['Key'])

Resource Method

boto3 also provides more convenient 'resource' methods, which are more Pythonic. For example:

import boto3

s3_resource = boto3.resource('s3')

for object in s3_resource.Bucket('bucket-name').objects.all():
  print(object.key)
