[Tutor] How arguments to the super() function works?

[Arup Rakshit]

I am writing an Flask app following a book, where a piece of python concept I am not getting how it works. Code is:

class Role(db.Model):
    __tablename__ = 'roles'
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(64), unique=True)
    default = db.Column(db.Boolean, default=False, index=True)
    permissions = db.Column(db.Integer)
    users = db.relationship('User', backref='role', lazy='dynamic')

    def __init__(self, **kwargs):
        super(Role, self).__init__(**kwargs)
        if self.permissions is None:
            self.permissions = 0

Here, why super(Role, self).__init__(**kwargs) is used instead of super().__init__(**kwargs) ? What that Role and self argument is instructing the super() ?

Thanks,
