How do I do this?

I just can't figure this out.

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>{{  }}</p>
{% endmacro %}

Here are some hints. There are three things to print out.

  • the first character of the email address, such as user.email[0]
  • replace second character up to the @ character of the email address with *
  • display the remaining @ character to the end of the email address

By splitting the email address on '@', the username would be the first entry, you can then loop over the characters in the results from .split('@')[0][1:] replacing them with asterisks.

Finally print out the @ removed by the split, and the second item from the split which contains the domain address. Note you'll likely need to use split again since the second term might not have been saved .split('@')[1]

Final, hint: If you are seeing extra blank spaces between characters in the result, add a minus sign inside of the template brackets to signify to jinja that extra white space should be removed: {{- or -}} or {%- or -%}.

Post back if you have more questions. Good luck!!
