    When using _inherit but leaving out _name, the new model replaces the existing one, essentially extending it in-place. This is useful to add new fields or methods to existing models (created in other modules), or to customize or reconfigure them.
    For example you can take idea from below code-

    class Extension0(models.Model):
        _name = 'extension.0'
    
        name = fields.Char(default="A")
    
    class Extension1(models.Model):
        _inherit = 'extension.0'
    
        description = fields.Char(default="Extended")
            record = env['extension.0'].create({})
            record.read()[0]
