Couldn't find function most_courses

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(teachers): count = 0 for teacher in teachers: count += 1 return count

def num_courses(teachers): count = 0 for value in teachers.values(): for course in value: count += 1 return count def courses(teachers): output = [] for courses in teachers.values(): output += courses return output

def most_courses(teachers): bid_num = 0 big_teacher = '' for teacher in teacher_dict: class_num = len(teacher_dict[teacher]) if (class_num > big_num): big_num = class_num big_teacher = teacher return big_teacher

            big_teacher = teacher
    return big_teacher

When you get a message that it "can't find" a function you have defined, it usually means there's a syntax error.

In this case, I see two issues:

  • the parameter name is "teachers", but the code body refers to "teacher_dict"
  • there's a spelling mismatch between "bid_num" (with a "d") and "big_num" ("g")
