Hi, can't understand the question, in the code everything looks and woks fine. What can be wrong? Thanks!!!
# 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(string):
return len(string)
def num_courses(string):
return sum((len(item) for item in string.value())

41,120 PointsThere are two errors in your code - you need to use .values() rather than .value(), and you are missing a closing ).
Comprehensions are a great way to do things in one line of Python that would otherwise take a few lines, but they also make it more difficult to find your errors. I'd recommend sticking to using multiple lines until you're more comfortable.
