Templating -Cheapest sequential electricity hours

Hello

I am ignorant and need your support in the code below which I have not been successful with

The idea is that I should see true/false when they are the lowest price

sensor:
  - platform: template
    sensors:
      cheapest_hours_energy_tomorrow:
        device_class: timestamp
        friendly_name: Cheapest sequential electricity hours
        value_template: >-
          {% set l=state_attr('sensor.nordpool_kwh_se3_sek_2_10_025', 'raw_today')|sort(attribute='value') %}
          {{ (now() >= l[0].start and now() <= l[0].end)
          or (now() >= l[1].start and now() <= l[1].end)
          or (now() >= l[2].start and now() <= l[2].end)
          or (now() >= l[3].start and now() <= l[3].end) }}
