2,611 PointsPlease 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 %}

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 %}
