Bummer! `courses()` seems to be missing some courses

I dont know why i will get the message "Bummer! courses() seems to be missing some courses"..I tested the code below in workspaces and it works just fine

dicts = {'Jason Seifer': ['Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],'Welby Obeng': ['Ruby Foundations','Ruby Foundations','Ruby Foundations', 'Ruby on Rails Forms', 'Technology Foundations'],
'Kenneth Love': ['Python Basics', 'Python Collections']}

def courses(dicts):
  classes = []
  for courses in dicts.values():
    for course in courses:
      classes.append([course])
  print(classes)

courses(dicts)

treehouse:~/workspace$ python stats.py
[['Python Basics'], ['Python Collections'], ['Ruby Foundations'], ['Ruby on Rails Forms'], ['Technology Foundations'], ['Ruby Foundations'], ['Ruby Foundations'], ['Ruby Foundations'], ['Ruby o n Rails Forms'], ['Technology Foundations']]

Write a function named courses that takes the dictionary of teachers. It should return a list of all of the courses offered by all of the teachers.

I figured it out...read the instructions wrong...i was making each course a list; as a result it gave a list full of lists...I removed [] around course and it was good
