Not sure why this code wont pass task 2

Question

It works in outside environments but for some reason it wont pass through the task?

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.

def num_teachers(a):
    return len(a.keys())

def num_courses(a):
    courses = {}
    for i in a:
        if type(a[i]) == type("String"):
            courses[i] = 1 
        else:
            courses[i] = len(a[i])

    print(courses)

well you are printing instead of returning, but also you don't need to type check, and you don't need to create a dictionary, you are just counting courses. create a counter variable and add to it 1 for each class in the values of the dictionary.

Hi Keifer, I feel like you're going a little too far on this one. First, for your function num_teachers: all you need is to return(len(a)) there's no need for all of that key() stuff. Second, for your function num_courses: if you were to make your var courses an int and assign it a 0... you could just write a for loop (for each in a:) that would continue to add ( courses += ) the len(a[each]). Then, you would just have to return(courses) when you finished your for loop.
