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

[Paul Warner]

First, thank you folks for answering these questions.  Some how my
list subscription got hosed up by my spam filter, so I just got a
chance to read these now.  My bad, sorry about that.

A comment like
# pylint: dynamic-attributes = foo, bar, baz

would be cool I think, or '*' as an option as well.

What would be even handier would be to specify the name of a python
list or dict where the list members or keys are the attribute names.
Of course this would need to be a class attribute, not an instance
attribute.  For example:

class MyClass(object):
    attrs = ['foo', 'bar', 'baz']
    # pylint: dynamic-attributes = attrs
    def __init__(self):
        for attr in self.__class__.attrs:
            setattr(self, attr, 'some value')

For the case that attributes are defined outside the class and passed
in to __init__ I can not think of a way to handle that one.
