Error: "Bummer: Didn't get the right output"
I'm trying to add a list of each key/value pair into a larger list, but apparently I'm not doing that correctly.
# 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(dictionary):
return len(dictionary)
def num_courses(dictionary):
course_list = []
for course in dictionary.values():
course_list += course
return len(course_list)
def courses(dictionary):
course_list = []
for x in dictionary.values():
course_list = course_list + x
return course_list
def most_courses(dictionary):
max_count = 0
teachers = " "
for teach, m_courses in dictionary.items():
if len(m_courses) > (max_count):
max_count = len(m_courses)
teachers = teach
return teachers
def stats(dictionary):
master_list = []
for teacher, course_count in dictionary.items():
return[teacher, len(dictionary.values())]

And an assignment or the "update" method of a dictionary might be useful in the loop body.
