I solved the task this way

def covers(params):
    result = []
    for key, values in COURSES.items():        
        if values & params:
            result.append(key)
    return result

One question when you have a for loop with 2 variables how do you know what element is assigned to what value. I've been seeing this a lot and I want to try to wrap my head around it. if you don't mind could you also explain your code I would really appreciate it.
