I run/host a community of Python new entry-level scripters. This seems perfect for them to see so they'll understand a little more about what they're seeing.
I'd welcome any other cheat sheets which you prefer, though. I was actually impressed at the clarity of this one because it's covered a lot of concepts that literally took a few forum posts to clarify for newbies.
Not a bad reference for newbies, but this lacks some important things (dictionaries, tuples, list comprehensions, lambdas etc.). Also, the arrow-style explanations don't lend well to a quick-search reference.
