Apart from it being "setattr" and not "setattrib", a simple
Color.BLACK = Color(0,0,0)
should have done the job here. However, what I had in mind was this:
class Color:
_colors = [ ("BLACK", (0,0,0)),
("WHITE", (1,1,1))
]
def __str__(self):
# try to locate a name
for name, rgb in Color._colors:
if self.rgb==rgb:
return name
# no name found, just format as a triplet
return "(%s, %s, %s)" % self.rgb
# add symbolic names
for name, rgb in Color._colors:
setattr(Colors, name, Color(rgb))
...which I got as suggestion on my question how to model C enumeration
lookalikes.
