class Student(models.Model):
default_selected_student = fields.Boolean(default=False)
if I select one student, the other student should be unselected. So, there can be only one who is selected.
How can i do that?

use api.constrains
@api.constrains('default_selected_student')
def _change_student_status(self):
if self.default_selected_student:
students = self.env['<_name>'].search([('id', '!=', self.id)])
for student in students:
student.default_selected_student = FalseOk... I think that you could do the the for with a single write, but don't know the exactly how to do it off my head.
Replace the <_name> with your models value for _name.
you could probably use api.depends
