im passing a variable into html from python through flask, is there a way to display a certain image if the value is less or more than a number?

Question

What I guess im asking is there a way to do logic in html? If not what would be the best way to do what I want to do?

is there a way to do something like

if {{ fkdr }} < 1:
    <img src="image.png" width="250" height="250">

Answer 1

If you are using Flask's render_template then yes you can use Jinja's if statement:

{% if fkdr < 1 %}
    <img src="image.png" width="250" height="250">
{% else %}
    Do something when there is no fkdr... or delete this else block leaving the endif below
{% endif %}
