Python Python Collections (2016, retired 2019) Sets Set Math

my function returns the right answers, why won't it pass the challenge?

i've tried a couple different methods, like converting the argument into a set by dong this:

a_set = {a_set}

but then if you pass in an actual set into the function and error shows up...

what to do...what to do?

i want a function that takes 1 set a paramater, and returns a list of courses whose values overlap with the given set parameter.

so first i created an empty list. then my next step was to go through each course now while looping through the course i want to check to see if the set of values of that course match with the given set. if it is a match add that course to my overlapping_course list. once the loop is complete show me the list

after checking my work i get bummer try again..

so it makes sense to me what am i missing? im excited i got this far by myself excitied to hear answers thank you very much!

Your code looks good to me. :+1:

So I tested it by pasting it directly into the challenge, and it passed task 1!

I've heard sometimes you need to restart the browser, give that a try.

Thank you Steven!
