"_If anyone is looking to build a production Python API, I would highly recommend **FastAPI**. It is **beautifully designed**, **simple to use** and **highly scalable**, it has become a **key component** in our API first development strategy and is driving many automations and services such as our Virtual TAC Engineer._"

`data.items()` ile, her dictionary öğesi için key ve value içeren tuple’lardan oluşan bir <dfn title="for döngüsüyle üzerinde gezinebileceğimiz bir şey; list, set vb.">yinelemeli nesne</dfn> elde ederiz.

Bu yinelemeli nesneyi `list(data.items())` ile düzgün bir `list`’e çeviririz.

  Suddenly she came upon a little three-legged table, all made of
solid glass; there was nothing on it except a tiny golden key,

doors of the hall; but, alas! either the locks were too large, or
the key was too small, but at any rate it would not open any of
them.  However, on the second time round, she came upon a low
