Please help with whitespace issue on a Macro

The code below (finally) worked for the hidden email challenge. Please tell me how to do this without putting everything on one line to avoid the jinja whitespace issue.

{% macro hide_email(user) %}

  {{ user.email.split('@')[0][0] }}{% for c in user.email.split('@')[0][1:] %}*{% endfor %}@{{ user.email.split('@')[1] }}

{% endmacro %}

Adding a hyphen - inside of the jinja2 braces will strip whitespace between them.

There would be no added whitespace between the closing -%} and the next opening {%-

As mentioned in this StackOverflow answer:

Change your loop to strip white spaces from the top AND bottom of the output (notice extra "-" at the for loop close):

     {% for key, value in querystring.items() -%}
          {{ key }}: '{{ value }}'
     {%- endfor %}

Thank you! It wasn’t very clear in the documentation.
