Program to search objects from an array of objects using filter method

class Student:
    def getStudentInfo(self):
        self.__rollno=input("Enter Roll Number : ")
        self.__name = input("Enter Name : ")
        self.__marks = int(input("Enter Marks : "))
        
    def printInfo(self):
        print("Roll No. : ", self.__rollno,", Name : ", self.__name, ", Marks : " , self.__marks)
        
    def SearchMarks(self,subject,min,max):
        if(subject=='marks' and (self.__marks >=min and self.__marks<=max)):
            return True
        else:
            return False

SL=[]
while(True):
    S=Student()
    S.getStudentInfo()
    SL.append(S)
    ch=input("Add More y/n?")
    if(ch=='n'):break

print("All students whose passed the exam are ")
RL=list(filter(lambda S : S.SearchMarks('marks',60,100),SL))
for S in RL:
  S.printInfo()

Output:

Enter Roll Number : 3
Enter Name : John
Enter Marks : 87
Add More y/n?y
Enter Roll Number : 5
Enter Name : Jane
Enter Marks : 654   45
Add More y/n?y
Enter Roll Number : 1
Enter Name : Nupur
Enter Marks : 99
Add More y/n?n
All students whose passed the exam are 
Roll No. :  3 , Name :  John , Marks :  87
Roll No. :  1 , Name :  Nupur , Marks :  99
