printing each element in a list -flask

For a flask app. I am trying to print each item in the list using Python code inside html There is something wrong with the code and treehouse editor is telling me that it all elements in the list are not printed.

Any help is much appreciated!

app.py
from flask import Flask, render_template

from options import OPTIONS

app = Flask(__name__)


@app.route('/')
def index():
    return render_template('options.html', options=OPTIONS)
templates/options.html
<ul>
{% for item in options %}
  <li>item['name'] </li>
  {% endfor %}
</ul>

Perhaps try wrapping item['name'] in {{ }}. Also, depending on whether you have a list of individual items or a list of dict items, you may be printing the wrong thing. If options is a list of strings, I believe you would just want {{item}}. However, if it's a list of dicts that each have a 'name' property, {{item['name']}} should do the trick.

Let me know if this helps.
