Python for .NET and IronPython

[John Salerno]

Hi all. I'm currently learning C#, and I'm also interested in learning 
Python (all of this just for fun, mind you), so it seems like a decent 
idea to want to integrate the two. But I don't quite understand the 
difference between these two Python implementations and I was hoping 
someone could explain.

Does either one require learning something different than the core 
Python language? With IronPython, would you actually be writing .NET 
code? I know Python for .NET is treated as a true language in the CLR, 
but I don't quite grasp what all this means for each language, and what 
the learning process for either language would be like as a result.

Thanks,
John
