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

I don't know what is wrong with my code. I keep getting the message that it's incorrect.

I've solved this in a few of different ways and it worked in workspaces each time but it doesn't work when I submit it.

# 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(dict):
    teachers = len(dict)
    return teachers

def num_courses(dict):
    courses = []
    for value in dict.values():
        courses += value
    return len(courses)

Hi Asia,

Which task are stuck on? I see that you've provided your code for tasks 1 and 2. When I copy-pasted your code into the challenge I was able to pass the first two tasks.

If you are having issues with task 2, I suggest you close and reopen your browser and then try copy-pasting your code above back into to the challenge.

If you are having issues with a later task, please update your question with your code that is failing the task.
