Code Challenge: Looping Through Items

The challenge task: "Your template has been given a list named options. Loop through each item in options and create an <li> inside the <ul>. Print out the name key of each item."

I am struggling with this one and not sure what I am missing. Can I get a clarification? Based on the wording of the challenge, I am assuming 'options' is a list of dicts? If so, then those dicts have a key 'name'? So when I loop through options, my li's will output item['name'].

thx

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>

looks like you have a space after you print the ['name'] value out right before the closing list item tag. 

<ul>
{% for item in options %}
  <li>{{ item['name'] }} </li> 
{% endfor %}
</ul>

this is probably whats causing your answer to be incorrect. the challenge engine is looking for the list item to contain the value itself, not the value with a space after it

remove the space. 

<ul>
  {% for item in options %}
  <li>{{ item['name'] }}</li>
  {% endfor %}

</ul>

Thanks for helping on this one, Stone Preston. I've updated the CC because it was too picky about those spaces.
