# Script not not working

it tells me my code is returning 5 classes instead of 18. Please anyone has a suggestion

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(teachers):
max_count = 0
L = []
for k in teachers.keys():
L.append(len(teachers[k]))

for i in teachers.keys():
if len(teachers[i]) == max(L):
return i

def num_teachers(teachers):
G = []
for Y in teachers.keys():
G.append(Y)
return len(G)

def stats(teachers):
A = []
B = []
for t in teachers.keys():
A.append(t)
A.append(len(teachers[t]))
n = 0
while n < (len(A) - 1):
B.append(A[n:n+2])
n = n + 2
return B

def courses(teachers):
X = []
for v in teachers.values():
X.append(v)
return X
```

So VERY close! You got 5 because you were appending the value of each teacher[key], which is a string. 5 teachers gives 5 strings gives 5 returned items. The method you need is `extend()` in place of `append()`:
```def courses(teachers):
