+interactive prompt, arbitrary precision integers, closures, list comprehension,
+generators, exception handling and more.  Still it is compact enough to fit and
+run within just 256k of code space and 16k of RAM.  MicroPython aims to be as
+compatible with normal Python as possible to allow you to transfer code with
+ease from the desktop to a microcontroller or embedded system.")
