Python Python Collections (2016, retired 2019) Dictionaries Teacher Stats

Teacher Stats Python Code Challenge

The block num_courses work in my own IDE on my computer, but when I try it in Treehouse it keeps saying for me to try again. :/

teachers.py
# 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.

values = {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'], 'Kenneth Love': ['Python Basics', 'Python Collections']}

def num_teachers(values):
    return len(values)

def num_courses(values):
    return sum(map(len, values.value()))

It should be values.values() on the last line. You forgot the "s" at the end of the second "values" But otherwise, good job!
