how do i pass each element of a set to a function?

Your question is basically “how can I loop without using a loop”. While it’s possible to do what you’re asking with out an explicit for loop, the loop is by far the clearest and best way to go.

There are some alternatives, but mostly they’re just changing how the loop looks, not preventing it in the first place. If you want to collect the return values from the calls to your function in a list, you can use a list comprehension to build the list at the same time as you loop:

results = [process_tuple(tuple) for tuple in set1]

You can also do set or dict comprehensions if those seem useful to your specific needs. For example, you could build a dictionary mapping from the tuples in your set to their processed results with:

results_dict = {tuple: process_tuple(tuple) for tuple in set1}

If you don’t want to write out for tuple in set1 at all, you could use the builtin map function to do the looping and passing of values for you. It returns an iterator, which you’ll need to fully consume to run the function over the full input. Passing the map object to list sometimes makes sense, for instance, to convert inputs into numbers:

user_numbers = list(map(int, input("Enter space-separated integers: ").split()))

But I’d also strongly encourage you to think of your current code as perhaps the best solution. Just because you can change it to something else, doesn’t mean you should.
