teachers.py... What an I doing wrong???

Question

I wish treehouse gave more verbose feedback, I tried the courses function in my terminal and it seemed to work fine. What am I missing?

For this step, make another new function named courses that will, again, take the dictionary of teachers and courses.

courses, though, should return a single list of all of the available courses in the dictionary. No teachers, just course names!

teachers.py

# 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(x):
    return len(x.keys())

def num_courses(x):
    total = 0
    for k in x:
        total += len(x[k])
    return total

def courses(x):
    all_courses = []
    for k in x.values():
        all_courses += k
    return all_courses

Your code worked for me when I tried it. This has happened to me a couple times also, I contacted support about it and this was their response.

"Can you please try the following to see if this helps?

If you are using Internet Explorer or Safari, please switch to Google Chrome or Mozilla Firefox. If you're already using Chrome or Firefox and you are still experiencing this issue, please disable your plugins. You can do this temporarily by opening a new window up in Incognito Mode (Chrome) or Safe Mode (Firefox). If a Code Challenge works within one of those two disabled plugin windows then the problem is a plugin on your browser that you'll need to remove."
