I am not understanding why it keeps saying "please try again". Thank you in advance!

Look like you have an extra trailing curly bracket at the bottom of your code.

Post back if you need more help. Good luck!!

If I literally cut-and-paste your above code:

def covers(topics):
    listing = []
    for thing in COURSES.items():
        a, b = thing
        if topics.intersection(b) :
            listing.append(a)
    return listing    

It passes Task 1. It doesn't look like you've started on Task 2 yet.

I did the exact same thing but it did not work with the other code on top
