Here my code def num_teachers(dictionary): return len(dictionary)
def num_courses(dictionary): total=0 for value in dictonary.values(): total+=len(value) return total
And it sasys can't finde num_courses
# 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):
total=0
for value in dictonary.values():
total+=len(value)
return total
