Could not convert string to float: '0.000 SBD'

[Pythonix]

The method get_comments() in the file post.py throws an error if the comments are sorted by total_payout_value (Python 3.5, Windows 10).

ValueError: could not convert string to float: '0.000 SBD'

I changed the method for me as follows:

  def get_comments(self, sort="total_payout_value"):
        """ Return **first-level** comments of the post.
        """
        post_author, post_permlink = resolveIdentifier(self.identifier)
        posts = self.steem.rpc.get_content_replies(post_author, post_permlink)
        r = []
        for post in posts:
            r.append(Post(post, steem_instance=self.steem))
        if sort == "total_payout_value":
            r = sorted(r, key=lambda x: float(
                x["total_payout_value"]**.replace(" SBD", "")**
            ), reverse=True)
        elif sort == "total_payout_value":
            r = sorted(r, key=lambda x: float(
                x["total_payout_value"]**.replace(" SBD", "")**
            ), reverse=True)
        else:
            r = sorted(r, key=lambda x: x[sort])
        return(r)

Of course this is just quick and dirty but it works for me until the devs fix it.
