For the most part, today's solutions let you write python modules in C/C++. So your core app is in python. I am thinking of the scenario where your core is in C++ and extendable in python for the business logic -- where the core can be a trading system engine, or a webserver for example. The rationale is python serves the algos/data scientists/quants use case really well, and C++ does the "engine" part of things really well.
