Keep your student_kit class in a separate file ( student_kit.py ) . Create a new file using the above code for creating three student inputs. Call the class student_kit from your new file and use the methods to show marksheet , certificate , attendance etc for each student.Use this code in your new file to link the class.

student.py
# Create the dictionary with three students
# For each student take marks in three subjeccts and attendance
# For each student display certificate using student_kit.

from student_kit import student_kit

my_dict={}

for i in range(0,3):
    n=input("Student Name : ")
    a=int(input("\n Enter maths marks: "))
    b=int(input("Enter physics marks: "))
    c=int(input("Enter Chemistry marks: "))

    p=int(input("Enter no of days present: "))


    my_dict.update({n:[a,b,c,p]})

print(my_dict)

for i in my_dict:
    obj=student_kit(i,"A")  #object  is created 
    obj.attendance(my_dict[i][3])
    print("Total Mark ",obj.marksheet(my_dict[i][0],my_dict[i][1],my_dict[i][2]))
    obj.certificate()
