Can someone please explain this.

So I made this line of code in my editor to be simple as possible without using another for block and it returns the email with letters changed. My question is why is not accepted? Just because the quiz mentions the for loop or because it's the code is not okey? I tried to pass the quiz in my way and i came up with this. Thank you.

from flask import Flask, render_template

app = Flask(__name__)

def index():
    class User:
        email = None
    user = User()
    user.email = 'kenneth@teamtreehouse.com'
    return render_template('user.html', user=user)
{% macro hide_email(User) %}
  <p>{{ User.email.replace(User.email.split('@')[0][1:], "*" * len(User.email.split('@')[0][1:])) }}</p>
{% endmacro %}

Excellent novel solution idea!! You are very close to correct. The len() function is not available in the template language. Instead use the length filter:

{% macro hide_email(User) %}
  <p>{{ User.email.replace(User.email.split('@')[0][1:], "*" * (User.email.split('@')[0][1:] | length)) }}</p>
{% endmacro %}
