Question

Does anyone have their code for part 4 of problem set 3? I am trying to figure out an easy way to eliminate exact matches from the tuple.

Answer 1

turn your tuples to lists (lists have lots of useful methods - like remove)
iterate over the list of match indices and
if the index is IN the exactmatch list, remove it

or

iterate over the list of exactmatch indices and
remove all instances of an exactmatch index from the match list

turn the list back into a tuple

the in and not in operators can be helpful
