"write a function named covers" - what am I doing wrong??

I can't see what's wrong with my code and having looked at other solutions, it seems to me like mine is among them. I've tried refreshing multiple times. Do I need to go get my morning coffee or is the solution correct and just not passing?

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(topics):
    keys = []
    for key, value in COURSES.items():
        if topics & value:
            keys.append(key)
    return keys

Whitespace issue. I took out all the whitespace in the for loop and then put it back in using the auto-indents and the code now passes.
