no_of_std = int(input("Enter number of students: "))  

result = {}  

for i in range(no_of_std):  

   print("Enter Details of student No.", i+1)  

   roll_no = int(input("Roll No: "))  

   std_name = input("Student Name: ")  

   marks = int(input("Marks: "))  

   result[roll_no] = [std_name, marks]    

print(result)  

# Display names of students who have got marks more than 75  

for student in result:
