Exercise Solution on Object Oriented Programming

1. Exercise on Object Oriented Programming
2. Create one student_kit class. Student object should have name and section.
   
   Method : mark_sheet , input: mark in three subjects and output should print individual mark and sum of it
   Method : attendance sheet , input: Number of working days , Number of days attended. Percentage of attendance should be presented.
   Method : Final certificate : should display passed from College name and section.
3. Update the above code to return Certificate showing total marks obtained and attendance in percentage by the student. ( Optional ) You can give grade A, B or C and decide Pass or Fail based on marks obtained ( as entered during generation of mark sheet )
4. Use the above code to take three students details from user as input and print one by one each student details. ( Hint : Use dictionary having a list to store the data )
5. 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.

# For each student take marks in three subjects and attendance
# For each student display certificate using student_kit.
