Python script to run N times HA scrip

1

Hello
I want to run this script , its supposed to call the script N times depends on the number of options in the input_select. I’m getting the following error:

Error executing script: ‘NoneType’ object is not callable

Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/homeassistant/components/python_script.py", line 166, in execute
    exec(compiled.code, restricted_globals, local)
  File "control.py", line 5, in <module>
TypeError: 'NoneType' object is not callable

My python script:

cortinas = hass.states.get('input_select.chooser').attributes['options']
Selected = []
for e in cortinas:
    Selected.set(e)
    option_select = {'entity_id': 'script.control_chooser','variables': Selected }
hass.services.call('script','turn_on',option_select)

Any Idea??
Thanks in advanced
