I have this line in a foor loop in flask and I want to set variable that would be increase each loop by a certain number. So f.e. margin-top is 50, 100, 150

<td style="margin-top:50px;">

Can anyone hint me a how to do such a loop, please? Is it possible to do it within this framework? Thanks

                <td style="margin-top:50px;">
                    <img src="{{url_for('static', filename=picture)}}" style="z-index:0;" />
                </td>
        <!--<div class="image_description">{{ picture.split('/')[-1].split('.')[0] }}</div>-->
        {% endfor %}

What would you go for all this trouble? Just create a class in css and add it to each <td>.

.myclass-with-50-margin-top {
    margin-top: 50px;
}

The result remains the same.

Edit:

{{rowCount = 0}}
{% for picture in pictures[item.id]%}

    <td style="margin-top: {{count += 25}}px">
         <img src="{{url_for('static', filename=picture)}}" style="z-index:0;" />
    </td>
{% endfor %}
