How can I return a list of all values from a dictionary??

I need to create a function that accepts a dict and returns a list of all the course values in a list, (ps the third method)

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(dict):
    return len(dict)

def num_courses(dict):
    course_count = 0
    for course in dict.values():
        course_count += len(course)
    return course_count

def courses(dict):
    course_list = []
    for course in dict.values():
        course_list.append(course)
    return course_list

I think your problem might be with using .append(). You will end up adding a list to the list, and the challenge wants one single list. I tried your code as-is, subbing only a different method call for .append(), and it worked. I hope that helps.
