When I program in C++, there are lots of things one must consider. Should this be const, public/private, virtual, should I create a class, should I first create an abstract base class, should I create a factory, should I implement the PIMPL idiom, should this be a template function. The list of concerns is nearly endless. When I write in Python I tend to mainly think about solving my problem. In C++ I will naturally think more about performance and in Python that concern comes only if something seems slow. I make no claims about which is better, just that the language definitely affects me and the approach I take.
