Flask macro task change test@bar.com to t**@bar.com

Question

Well, I'm not sure a did the right way and I'm a little bit out of ideas, I tried this on my computer working well, since we can use python in template with Jinja so added this idea but I can't pass the challenge

lunch.py

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def index():
    class User:
        email = None
    user = User()
    user.email = 'kenneth@teamtreehouse.com'
    return render_template('user.html', user=user)

templates/macro.html

{% macro hide_email(User) %}
{% set temp_list = User.email.split('@') %}
{% set temp_list2 = [] %}
{% final = '' %}
{% for letter in temp_list[0] %}
  {% if letter == list(temp_list[0])[0] and x not in temp_list2 %}
    {% temp_list2.append(letter) %}
  {% endif %}
  {% temp_list2.append('*') %}
{% endfor %}
{% set temp_list[0] = '@' %}
{% for letter in temp_list2[::-1] %}
  {% temp_list.insert(0, letter) %}
{% endfor %}
{% set final = ''.join(temp_list) %}
{{ final }}

Hi Darel,

I had a difficult time with this one as well. Although your logic looks good for running it in Python, it can be done without if statements or appending lists or any of that in Jinja. The trick is to print out each character one at a time rather than try to rejoin everything into a single variable at the end. You got the right idea using indexes and slices though.

You can assign temporary variables using "with":

{% with part_one, part_two = User.email.split('@') %}
    {{ part_one[0] }} .....

And you don't need to assign "*" or "@" to anything, they can simply be inserted where you want them outside of the curly braces. For example: {% ...code.. %}@{%...code...%}.

Also, make sure that everything that you want printed is coded on the same line, otherwise you will get whitespace between the characters.

Hope this helps,
