TTPython is a language and programming environment aimed at simplifying development of applications for large-scale, distributed, time-aware, energy-constrained systems such as smart cities and smart environments. TTPython includes a Python-derived programming language, a compiler, a graph interpreter, and interfaces to a cyber-physical simulator. Developing TTPython applications begins with understanding the core concepts of the language and the intended graph-based runtime systems. Please find the TTPython Source Code on Bitbucket.
