what function should i use to tidy up my code (extreme beginner)

My question is about the statistic_grab section, the whole code has complete functionality at the minute
but I'm unsure what function or method I should use to make my code efficient. As you can see, only some
of the data needed is in the code at present and its already getting ridiculously repetitive. All I am after is
guidance on what to use then I want to research how to use it and implement myself. Thank you in advance :)
