Use code tags
The def __str__ method most be inside the Student class.
Then you just print(s1) to get output from __str__

class Student: def __init__(self,name, roll_no): self.name = name self.roll_no = roll_no def __str__(self): return f"{self.name} has roll number {self.roll_no}." s1 = Student("Arjun", 1) print(s1) s1.name = "Dhananjay" print(s1) 

Output:
Arjun has roll number 1. Dhananjay has roll number 1.
