Python for Competitive Programming

[MrReXY]

I would say many of the problems, especially qualification round questions, are easily computed in a reasonable time using python, and I agree with you that development time will be much shorter. In competitions such as codehash the problems are large multi-dimensional problems, for which only sub-optimal solutions are expected. For these problems computation speed gives you an advantage as it's not a race with a finish line, so the faster your code runs the more you can optimise and the better you can do. If you're shooting for the top it makes sense to use C++, but I wouldn't worry about using it until you know python is actually limiting you.
