Question

Trying to loop over a list , and then show each element of that list in span element, but its not working first I want to check if length of that list is greater than 0 than loop over the list , I am not familiar with syntax , need help .

code:

  {%if len(prediction)>0%}
  {%for predict in prediction%}
  <span>{{predict}}</span>
  ​{% endfor %}

Answer 1

{% if prediction|length > 0 %}
  {% for predict in prediction %}
    <span>{{predict}}</span>
  ​{% endfor %}
{% endif %}

Try this, you can use "|length" to get length, if you want equal can use "length_is"

Like this:

{{ value|length_is:"0" }}
