Hmmm, python is not installed by default on Windows. Python3 is not installed by default on MacOS. Installing them is 30+meg and now your system is "infected" with python3 (I know if you use python every day this isn't an issue to you but as someone that's not a python expert and has run into version conflicts it's no fun).

So, AFAIK rust will generate a standalone exe, python, out of the box, will not so I want to give someone else my throw away solution, not requiring them to install python to use it might be a win?
