It really depends on what software you have installed. Quite a few packages require Python to function, and removing it will prevent/affect their functioning. This is one of the main advantages of Arch though: you start with a bare-bones system, and build from there as you need. One question though, why do you need to uninstall Python?
There’s definately places in NSW where you could experience SAD. Places in the Central West for example; Orange and Bathurst get quite gloomy during the winter.
