Pylint false positives

[Frank Millman]

Hi all

Pylint is flagging a lot of lines as errors that I would consider to be 
acceptable.

I have an abstract class ClassA with a number of concrete sub-classes. 
ClassA has a method which invokes 'self.method_b()' which is defined 
separately on each sub-class. Pylint complains that "Instance of 'ClassA' 
has no  'method_b' member".

First question - as a matter of style, is Pylint correct? If so, I could 
define 'method_b' in ClassA and raise NotImplementedError. Is this 
considered more pythonic? The downside is that I have quite a few of them, 
so it would add some clutter.

Second question - if my present code is not unpythonic, is there an easy way 
to suppress the error messages, without disabling 'no-member' altogether?

Thanks
