Python Flask Basics Character Builder Loop Nested Items

Flask Basic - Nested Loops Challenge

Hi,

I'm having trouble with the nested loop question, though I think it's my code that's the issue.

I'm unsure of the structure of the "Teachers" file, I can't tell if its like the options files for this project or a similar Challenge/Task we did earlier where each teacher had a course list in a dictionary.

Could you clarify the structure of the teacher file? Any small hints on the answer is also appreciated, though I'd like the chance to work it through.

Thanks, Fareeza

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>

    {% for course in teacher['courses']: %}
  <li> {{ course }} </li>

  {% endfor %}

  </li>

  {% endfor %}

</ul>

I don't know if you already solved this, but the structure of the dict elements in the teachers list does seem to be a string name and a list of courses. That part of your code is fine.

The problem, and I made the same mistake when I tried to correct your code, is that you haven't wrapped the courses list in a second < ul > field (sorry about the spaces in the tag, I don't know how to get inline code...). To quote the challenge text: "Now add a new < ul > inside of the < li > with a class of 'courses'. ...".

I hope that this is of some help without giving away to much ^^

Thanks! Funny how reading the instructions helps :)

I find it hard to program to specs when you don't have a full view of what's going on.

No problem ^^ Not having all the specs probably is fairly common working in an environment where, to many people, computers are more or less magic, so some of the... let's call them more vague exercises are probably quite informative. On the other hand, since it seems that they often want you to solve a problem in a certain way, sometimes some more information would be helpful ><
