I can't get this to work in the sandbox. Works on my system

I need help on why this won't work. It works for every case on my local system.

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(a_set):
    the_return_list = []

    for key in courses.keys():
        if a_set.intersection(courses[key]):
            the_return_list.append(key)

    return(the_return_list)

Python is case-sensitive, so the variable name courses isn't the same as COURSES.
