Does not generate anything in the output python code using clipspy

I am creating an expert system using clipspy, when I run the code in Python it throws nothing in the output and I have not been able to find the reason.

Python code:

import clips

DEFTEMPLATE_STRING = """
(deftemplate dormitorio
    (slot Presencia (type STRING))
    (slot Iluminación (type STRING)))
"""

env = clips.Environment()
env.build(DEFTEMPLATE_STRING)
env.load('test.CLP')
Dormitorio = env.find_template('dormitorio')
fact_Dormitorio = Dormitorio.assert_fact(Presencia = 'Si',
                                        Iluminación = 'Apagada')

env.reset()
env.run()

Clips file:

(defrule dormitorio
            (Presencia Si)
            (Iluminación Apagada)
=>
(printout t "Encender la iluminación del dormitorio." crlf)
(modify 1 (Iluminación Encendida))
)

What is expected is to output the print and modify the variable (Iluminación)?

You used dormitorio as the rule name when it needs to come after the rule name and an opening parenthesis for a fact pattern.

Don't use an integer constant with the modify command in the actions of the rule. Bind the fact matching the pattern to a variable and use that with the modify command.

(defrule r1
   ?d <- (dormitorio
            (Presencia Si)
            (Iluminación Apagada))
   =>
   (printout t "Encender la iluminación del dormitorio." crlf)
   (modify ?d (Iluminación Encendida)))
