It runs on my PyCharm but it won't pass the tests on Workspaces. Why?

I don't understand why this is not working. Anyone has a hint?

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):
    topic_list = []
    for key in COURSES:
        if topic.intersection(COURSES[key]):
            topic_list.append(key)
            return topic_list

You are very close to the correct answer. I pasted in your code and changed the indentation a tiny bit. The way you had it, it would work on some tests, but fail on some of the deeper tests run by the code challenge.

Good luck with Python!

def covers(topic):
    topic_list = []
    for key in COURSES:
        if topic.intersection(COURSES[key]):
            topic_list.append(key)
    return topic_list  # fix your indentation here to this.

Thanks for taking the time to check my code, Jeff!
