You do realize, that we are not doing math (read: number crunching) here? And again: What is needed is streamlining the algorithms (discussion on that already started as far as I could notice). An algorithm in O(n³) is always¹ worse than O(n). The constant factor added by the language difference is of no interest. > It's crazy that you're even trying to state it.

For a larger project, it often is more important to have readable and maintable code opposed to getting the last bit of performance. And Python is _far_ more readable and concise than C or C++ (imho). Due to lack of typechecking, I'm not so sure when it comes to maintainability though (there are test suites of course). - René ¹ For a large enough n.
