[Python-projects] is there a way to tell pylint about dynamic attributes?

I would prefer to have a way to tell pylint that a class has dynamic 
attributes without explicitly naming the attributes. In the best case 
explicitly naming the attributes is duplicating information, in the worst 
case it is not even possible to name the attributes since they might be 
different for different executions of the program (read from a user-provided 
data file, for example).

A possible syntax for this would be similar to what you proposed, but with a 
slightly different comment:
      # pylint: dynamic-attributes
or with a wildcard filter:
      # pylint: dynamic-attributes = *
or with a regex filter:
      # pylint: dynamic-attributes = .*
or similar to existing warning-suppression syntax:
      # pylint: disable-msg=E1101
In the last case, this suppression should not suppress warnings from code 
inside the class, but from code outside the class accessing attributes on 
the class.
