> Use Functions. This might seem counter intuitive, as calling function will put more stuff onto stack and create overhead from function returns, but it relates to previous point. If you just put your whole code into one file without putting it into function, it will be much slower because of global variables. Therefore you can speed up your code just by wrapping whole code in main function and calling it once, like so.
Wow, this is the one I couldn't expect. I always wrap the scripts in the main function out of pure perfectionism (or perhaps that's OCD) but the fact a script without it is going to run slower seems counter-intuitive and should really be among the first things taught.
