Need to return 18 from 5 classes sample input ( Task 4 )

Question

I got this error Bummer! You returned 5 courses, you should have returned 18.

how to returned 18 from all the course offered by teacher just 5

teachers.py

# 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):
  tmp = 0
  hasil = ""
  for x in dicts:
    if tmp == 0:
      tmp = len(dicts[x])
    elif tmp < len(dicts[x]):
      tmp = len(dicts[x])

    if len(dicts[x]) == tmp:
      hasil = x

  return hasil

def num_teachers(dicts):
  total = 0
  for x in dicts:
    total += 1
  return total

def stats(dicts):
  hasil = []
  for x in dicts:
    hasil.append([x, len(dicts[x])])
  return hasil

def courses(dicts):
  hasil = []
  for x in dicts:
    hasil.append(dicts[x])
  return hasil

You are Very close. In courses, each "x" in dicts is a list. There is one for each teacher. Using append() will add each of these lists to hasil as a single item, thus creating a list of five lists.

What you need is to extend hasil with the contents of each list using extend():

def courses(dicts):
  hasil = []
  for x in dicts:
    hasil.extend(dicts[x]) #< extend instead of append
  return hasil
