Just can't seem to get this challenge answered correctly. I feel like I'm right on the edge of it.

Please!

app = Flask(__name__)


@app.route('/')
def index():
    return render_template("teachers.html", teachers=TEACHERS)
templates/teachers.html 
<ul class="teachers">
  {% for teacher in teachers %}
    <li>
      <h2> {{ teacher['name'] }} </h2>
      <ul class="courses">
        {% for course in teachers['courses'] %}
          <li>{{ course['courses'] }}</li>
        {% endfor %}
      </ul>
    </li>
  {% endfor %}

      <h2> {{ teacher.name }} </h2>

      <ul class="courses">
        {% for course in teacher['courses'] %}
          <li>{{ course }}</li>
        {% endfor %}
      </ul>

    </li>
  {% endfor %}
</ul>

Wes;

Yes, you are very close indeed.

Take a look at your second for loop, we just want to print out the course inside the loop, correct? Not an attribute ['courses'] of course. That one small change in your code will make it work.

Post back if you are still stuck and happy coding,
Ken

Thanks Ken.

I managed to figure it out from another students question on the topic. I also , in the process, learned to browse the forum for answers more effectively. Can't believe it took me so long to figure out where other questions on the same topic were.
