Flask Basics: Character Builder: Loop Nested Items Pt 2

There seems to be an issue with my nested loop for the teachers courses, and after re-reading the html, I am not sure what the issue is with my template.

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.get('name') }}</h2>
    <ul class="courses">
      {% for course in teacher.get('courses') %}
      <li> {{ course }}</li>
      {% endfor%}
    </ul>
  </li>
  {% endfor %}
</ul>

That's an example of me not testing all of the possibilities. You have a space before your {{ course }} and that was throwing off my validation. I've updated the validation to be smarter & more forgiving. Thanks for finding that! Check your badges for a little treat.

Ah, well to be fair, in keeping with the standards of keeping your code "clean" that space shouldn't be there in the first place.. Thanks for the help!
