Courses Plus Student 1,372 Pointsthe course list
my code is here ,may I ask where is my mistake?
def courses(dictionary): all_class=[] for one_class in dictionary.values(): all_class.extend(one_class) return all_class
# The dictionary will look something like:
# {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'],
# 'Kenneth Love': ['Python Basics', 'Python Collections']}
#
# Each key will be a Teacher and the value will be a list of courses.
#
# Your code goes below here.
def num_teachers(x):
return len(x)
def num_courses(dictionary):
count=0
for teacher in dictionary:
count+=len(dictionary[teacher])
return count
def courses(dictionay):
all_clss=[]
for one_class in dictionary.values():
all_class.extend(one_class)
return all_class

def courses(dictionay):
When defining the function you have misspelled dictionary as dictionay
all_clss=[]
And you define the list as all_clss instead of all_class
You spell these words correctly everywhere else in your code, so If you fix those two typos then your code will work.
