I looked through the community question board but I still can't solve...Also, for the code above, is there a better (more concise) way to code the function?
# The dictionary will be something like:
# {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
# 'Kenneth Love': ['Python Basics', 'Python Collections']}
#
# Often, it's a good idea to hold onto a max_count variable.
# Update it when you find a teacher with more classes than
# the current count. Better hold onto the teacher name somewhere
# too!
#
# Your code goes below here.
def most_classes(dicts):
max_count = {'name': 'teacher', 'class':0}
for teacher in dicts:
value = len(dicts[teacher])
if value > max_count['class']:
max_count = {'name':teacher, 'class':value}
return max_count['name']
def num_teachers(teacher):
dicts = {'name':'teacher','class':'title'}
return len(dicts[teacher])

The number of teachers is equivalent to the number of key in the dict of teachers. This is the same as the len() of the dict:
def num_teachers(dicts):
return len(dicts)
