You are managing an event ticketing system and need to process ticket requests in the order of their priority. Each ticket request has a priority number associated with it.

    def __init__(self, ticket_id, priority):
        self.priority = priority

tickets = []
tickets.append(Ticket(1))
tickets.append(Ticket(2))
tickets.append(Ticket(3))
tickets.append(Ticket(4))
tickets.append(Ticket(5))

priority_queue = []
for ticket in tickets:
    heapq.heappush(priority_queue, (ticket.priority, ticket))

processed_tickets = []
while priority_queue:
    processed_tickets.append(heapq.heappop(priority_queue)[1])
