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

most_courses not working

I think i might have a compiler issue because my code seems to be correct. How do I avoid the compiler issues? thanks

# 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(teacherDict):
    return len(teacherDict)

def num_courses(teacherDict):
    total = 0
    for courses in teacherDict.values():
         total += len(courses)
    return total

def courses(teacherDict):
    course_list = []
    for courses in teacherDict.values():
        for course in courses:
    return course_list

def most_courses(teacherDict):
    max_count = 0
    teach_max = ""
    for teacher, courses in teacherDict.items():
        if max_count < len(courses):
            max_count = len(courses)
            teach_max = teacher
        elif max_count > len(courses):
        elif max_count == len(courses):
    return teach_max

Your code looks good. :+1:

Often, when code looks good posted in the forum but doesn't run in the challenge, it's because the indentation has mixed spaces and tabs. Be sure to use only one or the other consistently and you should pass.

You can also copy from above and paste directly into the challenge.
