Can you go into specifics about how any of these examples are non-obvious because the language is incredibly complex?

In the context of higher level and or dynamic languages, I'd argue that Python is rather low on the complexity scale

Yes, and some of those `hidden features' are just nice library functions that avoid adding features to the core language. Look at `enumerate' and `zip' for example, which allow Python to get away with one very simple for-loop.
