3,832 PointsNot understanding this Python Code Challenge.
I'm not understanding the second part of this code challenge. Could anyone offer some assistance, please?
Challenge Task 2 of 5 That one wasn't too bad, right? Let's try something a bit more challenging. Create a new function named num_courses that will receive the same dictionary as its only argument. The function should return the total number of courses for all of the teachers.
# 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(teachers):
count = 0
for teacher in teachers:
count += 1
return count
def num_courses(teachers):
for value in teachers.values():
return value.count(value)

Instead I set up a counter that incremented with the number of courses (found using the len() function) taught by each teacher.
