This passed the challenge, but there's an extra empty list I'd like to get rid of

def stats(teachers_dict):

    final_list = []
    name_num1 = []
    name_num2 = []
    for teacher in teachers_dict:
        if teacher in teachers_dict == "Jason Seifer":
            name_num1.append(teacher)
            name_num1.append(len(teachers_dict[teacher]))
        else:
            name_num2.append(teacher)
            name_num2.append(len(teachers_dict[teacher]))
    final_list.append(name_num1)
    final_list.append(name_num2)
        # print(teachers_dict[teacher])
    print(final_list)
    return final_list

stats(teachers_dict)

there's an extra empty list at the beginning of the line

[[], ['Jason Seifer', 3, 'Kenneth Love', 2]]

Now that I'm looking at it I don't think I needed the extra step of appending name_num1 and name_num2 into final_list.

This code is rather shorter and does the trick.

def stats(teachers):
    teachers_list = []
    for teacher, classes in teachers.items():
        teachers_list.append([teacher, len(classes)])
    return teachers_list
