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

Python Collections. Dictionaries. Teacher Stats Challenge. Task 4. The correct solution does not pass

Here is the code.

  1. How do I change it so that solution passes
  2. Maybe some improvements with /* packing/unpacking instead of loops?
# 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(d):
    for i in d:
    return ctn

def num_courses(d):
    for i in d:
    return ctn

def courses(d):
    for i in d:
    return l

def most_courses(d):
    span = 0
    for i in d:
        if len(d[i]) > span:
            span = len(d[i])
            s = i
    return s

Your code for most_courses (task 4) is correct. It's your code for courses (task 3) which is wrong. Presumably you already completed task 3 to reach task 4 and must have accidentally changed it, so I'll assume you don't need help with task 3. Let me know if you do want any hints though. I can assure you that your code for most_courses is correct.

Thanks again! You right.
