Why does my code not pass? Is it just syntax? The bummer simply says try again.

sets.py 
COURSES = {
    "Python Basics": {"Python", "functions", "variables",
                      "booleans", "integers", "floats",
                      "arrays", "strings", "exceptions",
                      "conditions", "input", "loops"},
    "Java Basics": {"Java", "strings", "variables",
                    "input", "exceptions", "integers",
                    "booleans", "loops"},
    "PHP Basics": {"PHP", "variables", "conditions",
                   "integers", "floats", "strings",
                   "booleans", "HTML"},
    "Ruby Basics": {"Ruby", "strings", "floats",
                    "integers", "conditions",
                    "functions", "input"}
}

def covers(topic):
    courses = []
    for course in set(COURSES.keys()):
        if len(course & topic) > 0:
            courses.append(course)
        return courses

There are two issues with your code:

  • Your return statement is inside the for loop. It needs to be unindented to bring it outside the loop.
  • You are currently checking if course intersects with topic. You need to check if the values you can access via COURSES[course] intersect with topic.
