CSS Flask Basics Character Builder Loop Nested Items

it's hard to understand what's wrong without presented content of TEACHERS. or I should also import COURSES?

Condition of the task : Now add a new <ul> inside of the <li> with a class of "courses". Inside this <ul> loop through the teacher's 'courses' key, creating an <li> for each course and printing the course. I can't figure out how get access to 'courses' ...

flask_app.py
from flask import Flask, render_template

from teachers import TEACHERS

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

</ul>

Inside your inner for loop, loop over the courses key/attribute for each teacher.

Therefore, the inner loop is:

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