I get a syntax error when executing the code using clipspy

Question

I don't see the bug in the syntax of the program, the error I get is this:

Reglas.CLP, Line 6: Syntax Error: Check appropriate syntax for defrule. ERROR: (defrule MAIN::DormitorioIluminación_Encender ?d <- (Dormitorio (Presencia Si) (Iluminación Apagada)) ?o <- (Otras (

Python code:

import clips
DEFTEMPLATE_STRING = """
(deftemplate Dormitorio
 (slot Presencia (type SYMBOL))
 (slot Iluminación (type SYMBOL)))
"""
"""
(deftemplate Otras
 (slot Hora (type INTEGER))
 (slot Estación (type SYMBOL)))
"""
env = clips.Environment()
env.build(DEFTEMPLATE_STRING)
env.load('Reglas.CLP')
Dormitorio = env.find_template('Dormitorio')
fact_Dormitorio = Dormitorio.assert_fact(Presencia = clips.Symbol('Si'),
 Iluminación = clips.Symbol('Apagada'))
Otras = env.find_template('Otras')
fact_Otras = Otras.assert_fact(Hora = '2000',
 Estación = clips.Symbol('Verano'))
env.run() 

CLIPS code:

(defrule Regla1
 ?d <- (Dormitorio 
 (Presencia Si)
 (Iluminación Apagada))
 ?o <- (Otras
 (Hora ?Hora))
 (test (and (>= ?Hora 1800) (< ?Hora 2300)))
=>
(printout t "Encender la iluminación del dormitorio." crlf)
(modify ?d (Iluminación Encendida))
)

What is the error?

Answer 1

You can't place multiple constructs in your call in the string you pass to the build method. The deftemplate Dormitorio is getting defined but not Otras.

• FernandoRT: now when I define Otras with the build I don't get this error, but now it says: in assert_fact raise PUT_SLOT_ERROR[ret](slot) TypeError: invalid type for slot 'Hora'
• Gary Riley: I'm not familiar with Python syntax, but my guess would be that you need to use 2000 in place of '2000'.
• FernandoRT: Yes, that was the error, thank you
