Icalendar module python can't import multiple events

[AlejandroPiquer]

I'm doing a proyect about importing some events that are written in a .txt to a .ics icalendar file but i have a problem about import more than one event. When i write the events in icalendar file, the events can't be imported because event=Event() imports all the the events multiple times. The first event is 3 times, the second 2 and the third 1, but the icalendar file can't be sorted. If anyone knows the coding to add multiple events to ical it would be very helpfull. Thanks a lot!
