Need help! I'm having trouble understanding.. What am I missing??

It's official: you're awesome at Python dictionaries! One last task and then you can take a well-deserved break!

In this last challenge, I want you to create a function named stats and it'll take our teacher dictionary as its only argument.

stats should return a list of lists where the first item in each inner list is the teacher's name and the second item is the number of courses that teacher has. For example, it might return: [["Kenneth Love", 5], ["Craig Dennis", 10]]

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 stats(my_dict):
    showcase = []
    for teacher,num_of_courses in my_dict.item():
        showcase.append = ([teacher,len(num_of_courses)])
    return showcase

You're very close...

2 errors found - does that point you in the right direction?

for teacher,num_of_courses in my_dict.item(): # just a missing letter on this line
        showcase.append = ([teacher,len(num_of_courses)]) # why are you using assignment - should be function call
