sVimPy is a very small Python virtual machine intended for use in microcontroller projects. At the moment, it supports about 3/4 of all opcodes used in python3k. Most data types are supported. The intended goal is to use this VM in environments like Atmel's ATmega chips (2-8kb RAM). The microcontroller bootloader is still missing (no arduinos left for experimentation). Classes are not supported. Features include: function calling, a stack based VM, garbage collection, very low memory usage, an interactive debugging console, dictionaries and tuples, iterations, VM single stepping (game loop usage is possible), C function calling, a small memory footprint, fast performance, the ability to be used as a library in other projects, a simple API + code, possible usage as a small deployment executable for Python projects.
Dyject is a dependency injection module for Python. Unlike other enterprise libraries used for Inversion of Control (IoC) which have classes which look like AbstractSingletonProxyFactoryBean, dyject is simple to understand and easy to use. It supports both Python 2.7 and Python 3, has no other dependencies, and uses standard configuration files to define and wire objects.
