Ah I see. I was confused because the variable was named like the parameter ("lbd").
So when leaderbord_sort is called, the reference to the given list object is assigned to lbd. With lbd = lbd[:] we create a new list by iterating through the old one and save the reference to the new list in lbd?
Why 'lbd = lbd[:]'?
