IronPython is a .NET implementation of the Python programming language. It has been a long time since I looked at Python but I believe that its significant features are dynamic typing and dynamic binding.
IronPython is getting a lot of attention now and you can use it on ASP.NET, Windows, Console, and Silverlight projects. It is interesting because it offers different ways to solve problems and write algorithms, so for me I’m not looking at it as a C# replacement but as a supplement to my C# and other skills, but I’ll write a review up as I get into the book.
I got the eBook pretty cheap and I’m converting it for reading on my Kindle now.
