# 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(dict_teachers):
return len(dict_teachers)
def num_courses(dict_teachers_and_courses):
result_list = []
for _ in dict_teachers_and_courses:
result_list = result_list + list(dict_teachers_and_courses[_])
return result_list
def courses(dict_teachers_and_courses):
result_list = []
for _ in dict_teachers_and_courses:
result_list = result_list + list(dict_teachers_and_courses[_])
return result_list
