Python Python Collections (2016, retired 2019) Dictionaries Teacher Stats

num_courses() function not working

I am not sure why my function isnt working. for each value list, i am trying to get its length, and add it to the total. This should work.

# The dictionary will look something like:
# {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'],
#  'Kenneth Love': ['Python Basics', 'Python Collections']}
# Each key will be a Teacher and the value will be a list of courses.
# Your code goes below here.

def num_teachers(teacherDict):
    return len(teacherDict)

def num_courses(teacherDict):
    total = 0
    for courses in teacherDict.values():
        total += len(courses)
    return total

I agree, it should work as-is.

Perhaps you're having a browser issue, try restarting your browser and then try the challenge again.
