Python Development Techdegree Graduate 8,466 PointsFor Loop not working as I expected
I'm not sure what I'm missing here. It says the amount of <li>'s listed is 0 which has me thinking it's not running the loop or it's not printing out anything. Thoughts?
from flask import Flask, render_template
from teachers import TEACHERS
app = Flask(__name__)
@app.route('/')
def index():
return render_template("teachers.html", teachers=TEACHERS)
<ul class="teachers">
{% for teacher in teachers %}
<li>
<h2 name="{{ teacher }}">{{ teacher.name }}</h2>
<ul class="courses">
{% for course in courses %}
<li name="{{ course }}">{{ teacher.courses }}</li>
{% endfor %}
</ul>
</li>
{% endfor %}
</ul>

Your mistake is here:
{% for course in courses %}
It should be:
{% for course in teacher.courses %} # the courses property (a list) for that specific teacher iteration
This passes both tasks
<ul class="teachers">
{% for teacher in teachers %}
<li>
<h2 name="{{ teacher }}">{{ teacher.name }}</h2>
<ul class="courses">
{% for course in teacher.courses %}
<li name="{{ course }}">{{ course }}</li>
{% endfor %}
</ul>
</li>
{% endfor %}
</ul>
I hope that helps.
Stay safe and happy coding!
