I’m trying to mock a singluar method from the boto3 s3 client object to throw an exception. But I need all other methods for this class to work as normal.
This is so I can test a singular Exception test when and error occurs performing a upload_part_copy

I’m using boto3 to get files from s3 bucket. I need a similar functionality like aws s3 sync
My current code is
#!/usr/bin/python
import boto3
s3=boto3.client(‘s3′)
list=s3.list_objects(Bucket=’my_bucket_name’)[‘Contents’]
for key in list:
s3.download_file(‘my_bucket_name’, key[‘Key’], key[‘Key’])
This is working fine, as long as the bucket ….
Using boto3, I can access my AWS S3 bucket:
s3 = boto3.resource(‘s3’)
bucket = s3.Bucket(‘my-bucket-name’)
Now, the bucket contains folder first-level, which itself contains several sub-folders named with a timestamp, for instance 1456753904534.
I need to know the name of these sub-folders for another job I’m doing and I wonder whether I could h….
I’m new to AWS using Python and I’m trying to learn the boto API however I noticed that there are two major versions/packages for Python. That would be boto and boto3.
What is the difference between the AWS boto and boto3 libraries?

I’m trying to do a “hello world” with new boto3 client for AWS.
The use-case I have is fairly simple: get object from S3 and save it to the file.
In boto 2.X I would do it like this:
import boto
key = boto.connect_s3().get_bucket(‘foo’).get_key(‘foo’)
key.get_contents_to_filename(‘/tmp/foo’)
In boto 3 . I can’t find a clean way to do the same thi….
In boto 2, you can write to an S3 object using these methods:
Key.set_contents_from_string()
Key.set_contents_from_file()
Key.set_contents_from_filename()
Key.set_contents_from_stream()
Is there a boto 3 equivalent? What is the boto3 method for saving data to an object stored on S3?
….
On boto I used to specify my credentials when connecting to S3 in such a way:
import boto
from boto.s3.connection import Key, S3Connection
S3 = S3Connection( settings.AWS_SERVER_PUBLIC_KEY, settings.AWS_SERVER_SECRET_KEY )
I could then use S3 to perform my operations (in my case deleting an object from a bucket).
With boto3 all the examples I fou….
I have a pandas DataFrame that I want to upload to a new CSV file. The problem is that I don’t want to save the file locally before transferring it to s3. Is there any method like to_csv for writing the dataframe to s3 directly? I am using boto3.
Here is what I have so far:
import boto3
s3 = boto3.client(‘s3′, aws_access_key_id=’key’, aws_secret_a….
I am using the Boto 3 python library, and want to connect to AWS CloudFront.
I need to specify the correct AWS Profile (AWS Credentials), but looking at the official documentation, I see no way to specify it.
I am initializing the client using the code:
client = boto3.client(‘cloudfront’)
However, this results in it using the default profile to co….
I have a boto3 client :
boto3.client(‘kms’)
But it happens on new machines, They open and close dynamically.

# better guidance to the user what needs to happen.
