i need help here

what am I doing wrong????

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(a):
    return len(a)
def num_courses(dic):
    number = 0
    for v in dic.values():
        number += len(v)
    return number
def courses(dic):
    course_list = []
    for v in dic.values():

        for a in v:
            course_list.append(a)
    return course_list
def most_courses(dic):
    m_courses = 0


    return teacher    
def stats(dic):
    fin_list = []
    for k , v in dic.items():
        pri_list = []
        pri_list.append(k)
        pri_list.append(len(v))
        fin_list.append(pri_list)

def most_courses(dic):
    m_courses = 0


    return teacher

this func is not true for challenge, for this func (most courses) ;

  • this function needs to compare length of values of teacher dictionary
def stats(dic):
    fin_list = []
    for k , v in dic.items():
        pri_list = []
        pri_list.append(k)
        pri_list.append(len(v))
        fin_list.append(pri_list)

return fin_list

this func seems like true

def stats(dic):
    fin_list = []
    pri_list = []
    for k , v in dic.items():
        pri_list = []
        pri_list.append(k)
        pri_list.append(len(v))
        fin_list.append(pri_list)

return fin_list

maybe you need to define this pri_list before for loop, this code should have no problem, try it
