I often convert python code to C++ and you'd be surprised how often the difference in loc is not that much. Certainly no hassle to do so. Not that I'm suggesting that one always should.

Several boost libraries are inspired by python and C++11 features all help to write C++ code that is surprisingly similar to python, with a bit of extra type sepcification. If you think otherwise I'd suggest you're probably thinking of the C++ of the 90s - a more C with classes, and not modern C++.

I often find it useful to develop and prototype in python and convert to C++. Most often I'm doing this because my python simulations can take days and the C++ versions hours. Often I find it is not just the performance critical areas, but it is easy enough just to wholesale convert the lot.
