Cambiar extensión del fichero para que se corresponda con el lenguaje de programación.

No es conveniente usar url con un valor "fijo" que se introduzca, para poder integrar este módulo con otros es recomendable utilizar referencias entre variables.

NO --> url = self.url
SI ---> url = self.getField(self.url)
