I have only 5 total courses in my dictionary why does function not pass and expect a list of 18 courses

My code here

my_dict = {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
'Kenneth Love': ['Python Basics', 'Python Collections']}

def courses(my_dict):
    course_list = []
    for courses in my_dict.values():
        course_list.append(list(courses))

    return course_list


courses(my_dict)

Figured it out it used .extend instead of append

def courses(my_dict):
    course_list = []
    for courses in my_dict.values():
        course_list.extend(list(courses))
    return course_list


courses(my_dict)

Yep, you have to add the content of the new list, not just the new list. Glad you figured it out!
