Dicts in scripts

Can dicts be used in scripts? The following:

state = hass.states.get('sensor.next_waterloo_train_status')
train_status = state.state

mappings = {
'ON TIME':'green',
'LATE':'orange',
'CANCELLED':'red',
}


hass.services.call('light', 'turn_on', { "entity_id" : 'light.lamp',
                                         'color_name': mappings[train_status]
                                         })

Gives error:

Traceback (most recent call last):
  File "/usr/src/app/homeassistant/components/python_script.py", line 107, in execute
    exec(compiled.code, restricted_globals, local)
  File "hello_world.py", line 17, in <module>

Hi i have the same problem … did you solve the problem ?

No solution I know of I’m afraid

Scripts support templating so try using the templating engine jinja - https://home-assistant.io/docs/configuration/templating/

{%- set myvar = {'dict': 'of', 'key': 'and', 'value': 'pairs'} -%}
{% print myvar['dict'] %}

That should print out ‘of’.

In your specific example you’d have to use templating instead of YAML for both the mappings and variable use.

I’ve discovered that lists are also not indexable.

hass.states.get(entities[0])
returns
NameError: name '_getitem_' is not defined

This has been fixed: https://github.com/home-assistant/home-assistant/pull/8541
