Python Jinja Variables Don't Add-CodePudding

I'm working on a project in flask and am trying a trick to run two foreach loops. I'm doing this by creating a variable and adding 1 to it after each loop like so:

{% set iteration = 0 %}

    {% for result in results %}
      <p id="{{ results_raw[iteration] }}">{{ result }}</p> <br>
      {% set iteration = iteration   1 %}
{% endfor %}

The iteration variable should go from 0 to 1 to 2 and so on. "results_raw" is a dictionary with 6 strings. When this code runs, the 0th string keeps printing over and over, meaning that the iterations variable is not increasing. What could be the cause of this?

CodePudding user response：

Instead of setting the iteration variable, you could access loop.index and loop.index0 inside a for loop

Refer to this documentation: https://jinja.palletsprojects.com/en/3.1.x/templates/

loop.index , The current iteration of the loop. (1 indexed)

loop.index0, The current iteration of the loop. (0 indexed)


{% for result in results %}
      <p id="{{ results_raw[loop.index0] }}">{{ result }}</p> <br>
      
{% endfor %}
