Jinja has a "center" formatting option, but how about "right align"?

Question

Say I have

{% for key,value in adict %}
{{key}}:{{value}}
{% endfor %}

How do I ensure that all of the keys are padded such that the output is

     something: 1
someotherthing: 3
  thelastthing: 2

edit: This is not a webpage I am working on, I am just getting string output for printing.

Answer 1

{{ key.rjust(20) }}:{{value}} did the trick

I did not know you could just call python string commands from the box. If someone has a more "jinja" solution, using pipes, I will give the answer to that.

Answer 2

Use the build-in Jinja2 filter called format. For example:

Left aligned string of width 20:

{{ "%-20s"|format(variable) }} 

Right aligned string of width 20:

{{ "%20s"|format(variable) }}

Your case:

{{ "%20s:%s"|format(key, value) }}
