I get error that the marker can't find "most_classes" but it is there... or am I missing something?
def most_classes(teacher_dict):
max_count = 0
busiest_teacher = 'None'
for teacher in teacher_dict:
num_classes = len(teacher_dict[entry])
if num_classes > max_count:
busiest_teacher = teacher
max_count = num_classes
return busiest_teacher

40,532 PointsLooks like you just had a mix up with the variable names:
# Change key from entry to teacher
num_classes = len(teacher_dict[teacher])
