Not sure what you mean here. "Class attributes" would normally mean
attributes that are shared by all instances of a class, as if you
were to do "SpeedTouchComm.rtuid = rtuid" in the above, instead of
using "self" which refers to an *instance*, not the class.
Also, what do you mean by "against the law"? The above example seems
to be exactly how *all* Python code works, where you pass values in
to the __init__ method and it dutifully assigns them to various names
in self. I don't think you're being clear, sorry.
Maybe the short answer will do: there's nothing wrong with the above.
It even exhibits good coding style! :-)
