多线E编E?/strong>
其实创徏U程之后Q线Eƈ不是始终保持一个状态的Q其状态大概如下：(x)
New 创徏
Runnable qA。等待调?br data-filtered="filtered" />
Running q行
Blocked d。阻塞可能在 Wait Locked Sleeping
Dead 消亡
U程有着不同的状态，也有不同的类型。大致可分ؓ(f)Q?br data-filtered="filtered" />
ȝE?br data-filtered="filtered" />
子线E?br data-filtered="filtered" />
守护U程Q后台线E）
前台U程
单了解完q些之后Q我们开始看看具体的代码使用了?/p>
1、线E的创徏
Python 提供两个模块q行多线E的操作Q分别是 thread ?threading
前者是比较低的模块，用于更底层的操作Q一般应用别的开发不常用?br data-filtered="filtered" />
因此Q我们?threading 来D个例子：(x)
import time
import threading
class MyThread(threading.Thread):
def run(self):
for i in range(5):
print('thread {}, @number: {}'.format(self.name, i))
time.sleep(1)
def main():
print("Start main threading")
threads = [MyThread() for i in range(3)]
for t in threads:
t.start()
print("End Main threading")
if __name__ == '__main__':
main()
q行l果Q?/p>
Start main threading
thread Thread-1, @number: 0
thread Thread-2, @number: 0
thread Thread-3, @number: 0
End Main threading
thread Thread-2, @number: 1
thread Thread-1, @number: 1
thread Thread-3, @number: 1
thread Thread-1, @number: 2
thread Thread-3, @number: 2
thread Thread-2, @number: 2
thread Thread-2, @number: 3
thread Thread-3, @number: 3
thread Thread-1, @number: 3
thread Thread-3, @number: 4
thread Thread-2, @number: 4
thread Thread-1, @number: 4
注意喔，q里不同的环境输出的l果肯定是不一L(fng)?/p>
