more elegant way when call parent method with the same name
Two ways to rewrite it:

When you know which version of the method you want to call you can name it directly, but in that case need to pass self as an argument:

    return Formatter.resp_in_hash(self, content)


Not necessarily more elegant.



Python 3 introduced a new cleaner super format for the common case when you want to step up from the current class and pass self (the first argument):

    return super().resp_in_hash(content)


This only works in python 3, though.
