Welcome to soCode, the social coding experiment. Four steps, fork -> edit -> open a pull -> merge Here are the rules! - Add a function with your github name as its name. - Your function can do anything and everything, as long as it finishes in a reasonable amount of time. No infinite loops, please. - Once your function is written, you can call it from anywhere else in the already existing execution chain. - Never entirely delete anyone else's function. Edit it if needed. - lafin() should be the last executing function, always - a call to lafin() must remain in __main__(). Let's see if we can make something meaningful out of this.
