Note, order matters in the conditional statement:

   if  search_list[idx] > search_list[maximum_score_index] or maximum_score_index == None :
      maximum_score_index = idx

Will raise an TypeError for search_list[None] TypeError: list indices must be integers or slices, not NoneType.

But this one since it hits the “maximum_score_index == None” first, it goes down to the conditional statement and skips the 2nd half.

   if maximum_score_index == None or search_list[idx] > search_list[maximum_score_index]:
      maximum_score_index = idx

I just learned this… thought I’d share.
