编写用多线程模拟火车站售票大厅的情形，包括：添加顾客、顾客离开、增加售票窗口、关闭售票窗口功能

好的，以下是一个简单的多线程模拟火车站售票大厅的程序：

import threading
import time
import random

class TrainStation:
    def __init__(self):
        self.customers = []
        self.tickets = 100
        self.ticket_windows = 5
        self.open = True

    def add_customer(self):
        self.customers.append("Customer {}".format(len(self.customers)+1))
        print("Added a customer. Total customers: {}".format(len(self.customers)))

    def remove_customer(self):
        if len(self.customers) > 0:
            self.customers.pop(0)
            print("Removed a customer. Total customers: {}".format(len(self.customers)))

    def sell_ticket(self):
        if self.tickets > 0:
            self.tickets -= 1
            print("Sold a ticket. Tickets left: {}".format(self.tickets))

    def add_window(self):
        self.ticket_windows += 1
        print("Added a ticket window. Total windows: {}".format(self.ticket_windows))

    def remove_window(self):
        if self.ticket_windows > 0:
            self.ticket_windows -= 1
            print("Removed a ticket window. Total windows: {}".format(self.ticket_windows))

    def close_station(self):
        self.open = False
        print("Train station closed.")

def customer_arrive(station):
    while station.open:
        time.sleep(random.randint(1,5))
        station.add_customer()

def customer_leave(station):
    while station.open:
        time.sleep(random.randint(5,10))
        station.remove_customer()

def sell_ticket(station):
    while station.open:
        time.sleep(1)
        if len(station.customers) > 0 and station.ticket_windows > 0:
            station.sell_ticket()

def add_window(station):
    while station.open:
        time.sleep(random.randint(10,20))
        station.add_window()

def remove_window(station):
    while station.open:
        time.sleep(random.randint(10,20))
        station.remove_window()

def close_station(station):
    time.sleep(60)
    station.close_station()

if __name__ == "__main__":
    station = TrainStation()

    threads = [
        threading.Thread(target=customer_arrive, args=(station,)),
        threading.Thread(target=customer_leave, args=(station,)),
        threading.Thread(target=sell_ticket, args=(station,)),
        threading.Thread(target=add_window, args=(station,)),
        threading.Thread(target=remove_window, args=(station,)),
        threading.Thread(target=close_station, args=(station,))
    ]

    for t in threads:
        t.start()

    for t in threads:
        t.join()

    print("Simulation finished.")

这个程序模拟了火车站售票大厅的场景，包括添加顾客、顾客离开、增加售票窗口、关闭售票窗口功能。在主函数中，我们创建了一个 TrainStation 对象，并创建了多个线程来模拟不同的行为。每个线程都会在一定的时间间隔内执行相应的操作，直到火车站关闭。最后，我们使用 join() 方法等待所有线程执行完毕，然后输出 "Simulation finished."。
