Hi,
Hoping you can help me with this code and understanding this looping better. I had no problem in the Python classes with iteration and dictionaries but I am stuck on this!
Thanks for your assistance!
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> {{ teacher['name'] }} </h2>
<ul class="courses">
{% for course in teachers %}
<li>{{ course['courses'] }}</li>
{% endfor %}
</ul>
</li>
{% endfor %}
</ul>

Treehouse Moderator 68,425 PointsBy saying
{% for course in teachers %}
course
is being assigned to each element in teachers
, which is a teacher.
Then
<li>{{ course['courses'] }}</li>
is effectively "teacher['courses']" which will produce a line for each teacher: 4 total
Instead, since you already have the teacher in the variable teacher
, you can get the teacher's courses using "teacher['courses']":
<ul class="courses">
{% for course in teacher['courses'] %}
<li>{{ course }}</li>
{% endfor %}
</ul>
