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

set Math task 1/2

Hi guys,

I'm at task 1/2 of Set Math. This is currently the code I prepared. It works alright in the launcher but the test does not accept it.

def covers (topic):
    set1=set([])
    result = 0
    for key in COURSES.keys():
        if topic in COURSES[key]:
          result = key
          set1.add(result)
        else:
          continue
    return(set1)

What am I doing wrong?

Thanks

I think you have gotten the wrong idea of what to do here. The challenge wants you to find every course that intersects with the topic given. You can picture the topic supplied as being a set with just one item and you have to compare that set to all the other courses (sets as well) to find which ones intersect and then return those.

If you are still struggling after reading this let me know and I'll give you my code.
