About this Book

IronPython is a radical project for Microsoft. It is the first project to be released under their Ms-PL (Microsoft Public License) open source license. It is also a radically different language from the ones that Microsoft has traditionally promoted for the .NET framework. IronPython is an implementation of the popular programming language Python for .NET. Python is an open source, object-oriented, dynamically typed language in use by organizations like Google, NASA and Pixar. Python is a multi-paradigm language, and brings new possibilities to .NET programmers: not just the added flexibility of dynamic typing, but programming styles such as functional programming and metaprogramming. For Python programmers the powerful runtime, ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
