I think it also has to do with security or perhaps even the insecurities (almost features)  in C++ (bufferoverflows due to pointers, etc). And don't forget that C++ is a programming language so it does not need an interpreter while Python (great fan btw) does. 

Time for me to pick this up again now, after reading this post. It's at least a decade ago I last finished a program in C++. But it's still my favorite. :) 

Thanks @brandonh, well written and upvoted! Same goes for you, @Joshpeterson and @dan.
