This is a python class wrapped around a number of common boto methods that I use to access AWS. Makes the code a little cleaner and abstracts away the details of making the connection to aws. At the moment it only contains methods to push and pull data to S3. WIll most likely add a method to retrieve a list files in a S3 bucket, and possibly add…

AwsConnect.py

import boto
import boto.s3.connection
# credentials.py should contain the access_key and secret_key which are needed for 
# the boto S3 connection
import credentials as cr

class AwsConnect(object):

    def __init__(self, bucket):
        self.bucket = bucket
        self.connect()

    # Connect to S3

    def connect(self):
        conn = boto.connect_s3(
                aws_access_key_id = cr.access_key,
                aws_secret_access_key = cr.secret_key,
                host = 's3-us-west-2.amazonaws.com',
                calling_format = boto.s3.connection.OrdinaryCallingFormat(),
                )

        # Connect to bucket
        self.cbucket = conn.get_bucket(self.bucket)

    def pull(self, filepathin, filepathout):
        key = self.cbucket.get_key(filepathin)
        key.get_contents_to_filename(filepathout)

    def push(self, filepathin, filepathout):
        key = self.cbucket.new_key(filepathin)
        key.set_contents_from_filename(filepathout)
