# 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))
