I cant seem to find whats wrong with my answer
# 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(my_dict):
count = 0
teacher = ""
for key in my_dict:
if(len(my_dict[key]) > count):

Tricky one this one! In your courses function you're currently using the append
method, and what that gives you in this case is actually a list of lists. The challenge, however, asks for a single list. Try replacing append
with extend
which will add the items of one list to the existing list.
Hope that helps!
