Question

How should I do a while ( x < y ) in jinja2?
I’ve seen the jinja2 docs, it seems like they only support for loop for a declared variable of array and while() is not supported at all.

Answer 1

I think your closest alternative with Jinja2 would be to use a for with range:

  {% range number from 3 to 6 %}
      {{ number }}
      (...)
  {% endrange %}

And you can pass the variables from your program to use them in the loop.
