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

Can you help me out here please I'm seriously stuck here.

it would be helpful if you can show me how to tackle this problem.

# 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(teacher):
    teacher_count = 0
    for key in teacher.keys():
        teacher_count += 1
    return teacher_count

def num_courses(teacher):
    course_count = 0
    for value in teacher.values():
        for each in value:
            course_count += 1
    return course_count

def courses(teacher):
    courses = []
    for value in teacher.values():
        courses += value
    return courses

def most_courses(teacher):
    max_count = 0
    for key in teacher.keys():
        for value in teacher.values():
            max_count = max(value)
    return key max_count

Hi Ian

Which part of the challenge are stuck with ? is it the most_courses part of the challenge, if so see below

def most_courses(mydict):
    max_count = 0
    teacher = None
    for key,val in mydict.items():
        if len(val)> max_count:
            teacher = key
        max_count = len(val)
    return teacher

Thanks a lot Cormack
