Not really the same but I typically just do something like this to prevent magic numbers sprinkled all over my consuming code...

<code>

class Section(TransformerCommon): """ working model """ TEMPERATURE_COLD = 20

    NONE = 0
    END = 1
    BOTH = 2
    END_INSULATION_LOC_CHOICES = (
        (NONE, "None"),
        (END, "End"),
        (BOTH, "Both"),
    )

... end_ins_location = models.IntegerField( choices=END_INSULATION_LOC_CHOICES, verbose_name="End Insulation Location") ... try: if self.end_ins_location == Section.NONE: ... elif self.end_ins_location == Section.END: ... elif self.end_ins_location == Section.BOTH: ... else: ...
