红绿灯实例，event事件

import time, threading

event = threading.Event()

# 交通灯
def lighter(): count = 0 while True: if count < 5:  # 绿灯 event.set()  #设置标志位 print("\033[42;1m 绿灯亮\033[0m") elif count > 10: count =0  # 清零重新计数 else:  # 红灯 event.clear()  # 清空标志位 print("\033[41;1m 红灯亮\033[0m") time.sleep(1) count += 1

# 车辆
def car(name): while True: if event.is_set():  # 绿灯亮 print("[%s]绿灯行..." % name) time.sleep(1) else: print("[%s]红灯停!!!" % name) event.wait()  # 等待标志位设定 print("\033[34;1m绿灯出发\033[0m")

# 启动交通灯
t_lighter = threading.Thread(target=lighter)
t_lighter.start()

# 放入车辆
t_car1 = threading.Thread(target=car, args=("奥迪车",))
t_car2 = threading.Thread(target=car, args=("大众车",))
t_car1.start()
t_car2.start()

# 备注，\033在pycharm中有效果
