teacher stats task 3 of 5. Somebody help! I'm stuck

I keep getting the first item in the list. Somebody help!

# 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(treehouse):
    treehouse_key =   treehouse.keys()
    return len(treehouse_key)

def num_courses(treehouse):
    count = 0
    for teacher in treehouse:
        count += len(treehouse[teacher])
    return count

def courses(treehouse):
    the_list = []
    for tree in treehouse:
        return the_list

Hi Yusuf,

You have a bug in your indentation level for your return statement. Look closely at that line and consider when your function will return compared to when you intend for it to return.
