# working on final project to combine all the learnt concepts into 1
# problem statement.
#The CTO wants to monitor all the computer usage by all engineers. Using Python ,
# write an automation script that will produce a report when each user logged in and out,
# and how long each user used the computers.



# writing real script:
# first sort all the processes by date using a function:
def get_event_date(event):
    return event.date
#get current user and pass the sorted date function
# first sort all the processes by date using a function:
def get_event_date(event):
    return event.date
#get current user and pass the sorted date function
