# You are working for the school Principal. We have a database of school students:
school = {'Bobby','Tammy','Jammy','Sally','Danny'}
#during class, the teachers take attendance and compile it into a list.
attendance_list = ['Jammy', 'Bobby', 'Danny', 'Sally']
#using what you learned about sets, create a piece of code that the school principal
# can use to immediately find out who missed class so they can call the parents.
# (Imagine if the list had 1000s of students.
# The principal can use the lists generated by the teachers + the school database to use python and make his/her job easier):
# Find the students that miss class!
print(school.difference(attendance_list))
