What is Python?

What is Python?Python is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days.- Taken from the official Python site, python.org

Who’s Using Python?Python plays a key role in our production pipeline. Without Python a project the size of Star Wars: Episode II would have been very difficult to pull off. From crowd rendering to batch processing to compositing, Python binds all things together. -- Tommy Burnette

Who’s Using Python?Python has been an important part of Google since the beginning. -- Peter Norvig.http://code.google.com/appengine/Python application servers and Python scripting to create the web UI for BigTable (their database project)

Who’s Using Python?We chose Python because it provides maximum productivity, code that's clear and easy to maintain, strong and extensive (and growing) libraries, and excellent capabilities for integration with other applications on any platform. -- Steve WaterburyWorkflow automation servers

Python’s Weaknesses Can be slower than compiled C or C# Relies on a locking mechanism called the Global Interpreter Lock (GIL) in multi-threadingImplementations in other languages get around – specifically Jython and IronPython

What is IronPython?IronPython is the open source .NET implementation of the Python programming language, giving Python programmers the benefits of the .NET libraries while still maintaining compatibility with straight Python.

Python Recommended ReadingPython Cookbook by Alex Martelli, Anna Ravenscroft, and David Ascher (ISBN: 978-0596007973)Python Programming for the Absolute Beginner by Michael Dawson (ISBN: 978-1598631128)Core Python Programming by Wesley Chun (ISBN: 978-0132269933)

IronPython Recommended ReadingI recommend technical books typically based on their reference value, as I usually get bored within the first few sentences and end up turning them into references rather than reading through them. This book, however, was one that I read cover-to-cover...Overall, I would recommend IronPython in Action for anyone wanting to learn IronPython.– Sarah DutkiewiczThe Coding Geekette (reviewed for Manning Publications)http://www.ironpythoninaction.com
