Django override save method

We can override the save method into two ways,

1)
 class Blog(models.Model):
         name = models.CharField(max_length=100)
         tagline = models.TextField()

       def save(self, *args, **kwargs):
             do_something()
             # Call the "real" save() method in the base class 'models.Model'
             super(Blog, self).save(*args, **kwargs) <-----
            do_something_else()

 is equal to

2)
  class Blog(models.Model):
           name = models.CharField(max_length=100)
           tagline = models.TextField()

         def save(self, *args, **kwargs):
              do_something()
              # Call the "real" save() method in the base class 'models.Model'.
              models.Model.save(self, *args, **kwargs) <----- Note: self
              do_something_else()
