Challenge task 2 of 5

I'm trying to work the second step of the challenge. I'm getting confused. I tried running my code through the repl(?) but I keep receiving File "<stdin>" line 2 syntax error: can't assign to function call. I'm confused on where my syntax error lies.

# 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(school):
    return len(school)

def num_courses(school):
    c = 0
    course_count = 0
    for course in school:
        course_count() = course_count + len(school.value(c))
        c = c+1
    return course_count

That would be because you're calling course_count()

  • You can just replace it with course_count

Like this

course_count = course_count + len(school.value(c))

This is an example of a correct answer that you can try if you're really stuck, make sure you try before though

def num_courses(dictionary):
    course_count = 0
    for teacher, courses in dictionary.items():
        course_count += len(courses)
    return course_count
