本文实例讲述了python多线程高级锁condition简单用法。分享给大家供大家参考，具体如下：
多线程编程中如果使用Condition对象代替lock, 能够实现在某个事件触发后才处理数据, condition中含有的方法:
def __enter__(self):
return self._lock.__enter__()
def __exit__(self, *args):
return self._lock.__exit__(*args)
代码:
import threading
from threading import Condition
# condition
class XiaoAi(threading.Thread):
def __init__(self, cond):
self.cond = cond
super().__init__(name="xiaoai")
def run(self):
self.cond.acquire()
self.cond.wait()
print('{}:ennn. '.format(self.name))
self.cond.notify()
self.cond.wait()
print('{}:好嗒. '.format(self.name))
self.cond.release()
class TianMao(threading.Thread):
def __init__(self, cond):
super().__init__(name="tiaomao")
self.cond = cond
def run(self):
self.cond.acquire()
print('{}:hello ~ xiaoai. '.format(self.name))
self.cond.notify()
self.cond.wait()
print('{}:我们来念一首诗吧! . '.format(self.name))
self.cond.notify()
self.cond.release()
if __name__ == '__main__':
condition = Condition()
xiaoai = XiaoAi(condition)
tianmao = TianMao(condition)
# 启动顺序很重要
xiaoai.start()
tianmao.start()
打印结果:
tiaomao:hello ~ xiaoai.
xiaoai:ennn.
tiaomao:我们来念一首诗吧! .
xiaoai:好嗒
总结:
这个比较鸡肋
希望本文所述对大家Python程序设计有所帮助。
