Python Python Collections (2016, retired 2019) Dictionaries Teacher Stats

I'm not sure what's going on here.

I am having a hard time breaking down the problem and figuring out which solutions to use for them. Any pointers or advice would be appreciated.

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.
teachers={"cliff":["music", "photography", "writing"], "fulmer":["band","theory"], "cindy":["trumpet","horn"]}

def num_teachers(teachers): 
    return len(teachers.keys())

def num_courses(teachers): 
    courses=0
    for i in teachers: 
        courses+=len(teachers[i])
    return courses 

def courses(teachers): 
    course_list=[]
    for i in teachers.values(): 
        course_list+=i
    return course_list

def most_courses(teachers): 
    max_count=0
    most=""
    for i in teachers.values(): 
        max_count+=1

In your loop, you will probably want to check if the count of courses in the current item is greater than the max_count. If it is, you would copy that count into max_count and also store that teacher's name in most. After the loop has finished you can return most.
