I'll go first, but I can't really decide. List Comprehensions, from Haskell or Python for example, are super amazing. For a mathematician like me, the notation is very intuitive and they make for concise and elegant code. Generators are also a contender for my personal number one. Fast, memory efficient and semantically beautiful, they are defined like a function, but behave like a list.

I think that Python's context managers are brilliant (they were my favorite construct before) but quite far from the power of generators, especially since 3.3
