help please

what when wrong?

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(abc):
    return len(abc)

def num_courses(abc):
    summ = 0
    for a in abc:
        summ += len(abc[a])
    return summ

Hi Daniel,

The issue is very minor - you have a mix of tabs and spaces in your code. Specifically, you have a tab in front of the return statement on the last line, whereas the rest of your code is indented with spaces.

If you replace that final tab with 4 spaces, everything will work!
