Recently I have made a brief exploration of local job market and have found a simple fact – Python is greatly misunderstood and as a result – extremely underestimated.

Having an experience of being employed by different software developing companies, I have heard many times from technical people that Python is slow and doesn’t have a real threading mechanism and due to the lack of static types it’s error-prone; that some of the “basic” OOP stuff is missing there and this is more like a toy language with no real use in production environment… So I felt a deep need to write an introduction to Python for potential users, employers and to all who may be interested. It might be of great use for business owners and start-up runners as well as for technical people.

Introduction.

1. “Python is a programming language that allows you to work more quickly and integrate your systems more effectively. You can learn to use Python and see almost immediate gains in productivity and lower maintenance costs.” – From my personal experience the development on Python is about 3 times faster then on Java.

2. “Python runs on Windows, Linux/Unix, Mac OS X, and has been ported to the Java and .NET virtual machines.” – and I would add also all of them.

3. “Python is free to use, even for commercial products, because of its OSI-approved open source license.”

The world is changing. Reactive Manifesto.

First of all I would like you to introduce a reactive application manifesto.

It has been recently created to name the changes that are remarkably  taking place in nowadays requirements to a network application. Reactive application manifesto lists the rules that application has to comply with, namely – scalability, responsiveness and resilience. It clearly says that scalability and responsiveness are all about asynchronous programming models (APM).

Responsiveness.

A year ago I’ve written a post about asynchronous programming with python, where I explained the advantages of APM over threading model. There I claimed that Python is actually excels APM in respect to simplicity of code writing. Having one of the largest official repository of open source code (36195 packages as of time of writing the current post), Python can offer many different libraries that make it dead-easy to write an APM based code. While the most advanced of them is Twisted – event driven networking engine.

Gregory Begelman describes here how we built APM crawlers system on top of scrapy that is being able to scrape simultaneously 2000 domains on one machine with 8 cores and 32G of RAM. In this post I elaborate it even further.

Scalability and Resilience.

Today the major players on the market such as Google, Facebook, Yahoo, Youtube and many others use Python as part of their core infrastructure.

Such well-known and commonly used computing systems as  Amazone Web ServicesGoogle AppEngineAppache Hadoop and Nokia Disco have been integrated with Python as well.

Thereby, Python is perfect for reactive application model that is described above. Considering its simplicity in use and its open source nature with a mature community and huge repository, I conclude that Python is an optimal, best and the most efficient choice for today’s network application programming needs and challenges.
