PEP8 overriding

I have recently adopted PyCharm as my IDE of choice for my Python projects, partly because of its PEP8 integration, even to the point of checking my comments.  But occasionally it goes overboard.  And I'd be satisfied if I could just tell it "I know, and I'm right".  Here is a case where an "Add word to dictionary" option would be lovely.:

def __init__(self, *args, textvariable=None, **kwargs):

"textvariable" is flagged as a "typo".  I'd like to have "clean" code, but I don't know how to override this.
