The operator module exports a set of efficient functions corresponding to the intrinsic operators of Python.

9.9. operator — Standard operators as functions

For example, operator.add(x, y) is equivalent to the expression x+y. The function names are those used for special class methods; variants without leading and trailing __ are also provided for convenience. The functions fall into categories that perform object comparisons, logical operations, mathematical operations, sequence operations, and abstract type tests. The object comparison functions are useful for all objects, and are named after the rich comparison operators they support: operator.lt(a, b)operator.le(a, b)operator.eq(a, b)operator.ne(a, b)operator.ge(a, b)operator.gt(a, b)operator. Perform “rich comparisons” between a and b. The logical operations are also generally applicable to all objects, and support truth tests, identity tests, and boolean operations: operator.not_(obj)operator.

How to use *args and **kwargs in Python Or, How to use variable length argument lists in Python.

How to use *args and **kwargs in Python

The special syntax, *args and **kwargs in function definitions is used to pass a variable number of arguments to a function. The single asterisk form (*args) is used to pass a non-keyworded, variable-length argument list, and the double asterisk form is used to pass a keyworded, variable-length argument list. Here is an example of how to use the non-keyworded form. This example passes one formal (positional) argument, and two more variable length arguments. def test_var_args(farg, *args): print "formal arg:", farg for arg in args: print "another arg:", arg test_var_args(1, "two", 3) Results:

Boto 3 Documentation — Boto 3 Docs 1.3.1 documentation. New Event Notifications for Amazon S3. Many AWS customers have been building applications that use Amazon Simple Storage Service (S3) for cost-efficient and highly scalable persistent or temporary object storage.

New Event Notifications for Amazon S3

Some of them want to initiate processing on the objects as they arrive; others want to capture information about the objects and log it for tracking or security purposes. These customers have been asking for a reliable and scalable way to be notified when an S3 object is created or overwritten. Build a simple distributed system using AWS Lambda, Python, and DynamoDB — AdRoll. Build a simple distributed system using AWS Lambda, Python, and DynamoDB — AdRoll. AWS inventory details in CSV using lambda. Here at Powerupcloud, we deal with a wide variety of environments and customers of varying sizes - we manage Infra hosted on AWS for a one-man startup to huge enterprises.

AWS inventory details in CSV using lambda

So it is necessary for our support engineers to get familiar with new features and also continue to hone their skills on existing AWS technologies. We have a dedicated AWS account for R&D and all of our support engineers have access to it. To avoid a bill shock at the end of the month, we wanted to collect an inventory of resources every day in CSV format, store it on S3 and trigger an email.

AWS inventory details in CSV using lambda. The Context Object (Python) - AWS Lambda. While a Lambda function is executing, it can interact with the AWS Lambda service to get useful runtime information such as: How much time is remaining before AWS Lambda terminates your Lambda function (timeout is one of the Lambda function configuration properties).The CloudWatch log group and log stream associated with the Lambda function that is executing.The AWS request ID returned to the client that invoked the Lambda function.

The Context Object (Python) - AWS Lambda

You can use the request ID for any follow up inquiry with AWS support. If the Lambda function is invoked through AWS Mobile SDK, you can learn more about the mobile application calling the Lambda function. AWS Lambda provides this information via the context object that the service passes as the second parameter to your Lambda function handler. For more information, see Lambda Function Handler (Python). The following sections provide an example Lambda function that uses the context object, and then lists all of the available methods and attributes. Note. AWS Lambda Functions in Go - There’s no place like. Update 1: Thanks @miksago for the much more robust node.js wrapper.

AWS Lambda Functions in Go - There’s no place like

I guess you can now see the reason why I wanted to avoid node :-) I’m a big fan of AWS, and every year I get super excited about a new technology/service they release. Last year, I spent too much time marvelling about the simplicity and beauty of AWS Kinesis. And in the meantime, I’ve been applying the same principle on a smaller project I’m working on. But this year I was stoked about AWS Lambda.

But after skimming through the documentation, I’ve realised that the only supported runtime is Javascript (via Node.JS). Fortunately, it’s well known that you can statically cross compile your Go binary. Just uploaded a cross compiled Golang binary to AWS Lambda and called it from the node.js function: it works flawlessly #happy #hack— Ruben Fonseca (@rubenfonseca) November 21, 2014. Hacking with AWS Lambda and Python. Ever since AWS announced the addition of Lambda last year, it has captured the imagination of developers and operations folks alike.

Hacking with AWS Lambda and Python

Lambda paints a future where we can deploy serverless(or near serverless) applications focusing only on writing functions in response to events to build our application. It’s an event-driven architecture applied to the AWS cloud, and Jeff Barr describes AWS Lambda quite well here, so I’ll dispense with all the introductory stuff. Example of python code to submit spark process as an emr step to AWS emr cluster in AWS lambda function.

FlyTrapMind/saws: A supercharged AWS command line interface (CLI). Python - How to launch and configure an EMR cluster using boto. Elastic Map Reduce with Amazon S3, AWS, EMR, Python, MrJob and Ubuntu 14.04. This tutorial is about setting up an environment with scripts to work via Amazon's Hadoop implmentation EMR on huge datasets. With dataset I mean extremely large datasets and a simple yet powerful grep does not cut it any more for you. What you need is Hadoop. Setting up Hadoop the first time or scaling it can be to much of an effort, this is why we switched to Amazon Elastic Map Reduce, or EMR, Amazon's implementation of Yahoo! 's Hadoop, which itself is an implementation of Google's MapReduce paper.

Amazon's EMR will take care of the Hadoop architecture and scalability; in the likely case one cluster is not enough for you. So let me outline the architecture of the tools and services I have in mind to get our environment going. You will need your Access Key, Private Key and usually a private key file to access AWS from programatically. cntml.
