2,538 PointsNested loops confusing me
How do I nest a 'for' loop in jinja syntax? Should I type{{% for item in items %}} twice?
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 item in teachers %}
<li>
<h2>{{item.name}}</h2>
<ul class='courses'>
{% for item in courses %}
<li>{{item.name}}</li>
{% endfor %}
</ul>
</li>
{% endfor %}
</ul>

Treehouse ModeratorGreetings Ngqabutho!
Great job so far! You can definitely keep on nesting those for loops, but if you are naming everything {% item in ____ %} it could get a bit confusing. So the first thing I recommend is saying something like {% for teacher in teachers %}, {% for student in students %}, etc.
So for this part of the challenge you are asked to iterate through the teacher's 'courses' key. You have already done this for the 'name' key by saying {{ teacher.name }}. Now to access the course key in the for in loop you need to iterate for course in teacher.courses (can also be done as teacher['courses']) Then in your li tags we want course to be printed (course.name will not work because name is a key for teacher) so a simple {{ course }} will work!
Hope this helps and happy coding! 💚💚💚

Treehouse TeacherHi there, Ngqabutho Moyo! The problem with the nested loop really is that you are re-defining item. This is going to confuse things 
for loops. Like for teacher in teachers and for course in teacher.courses.
Hope this helps!
