一、线程创建方法
1. 普通创建

import threading
def run(name):
for i in range(3):
print(name)
if __name__ == '__main__':
t1 = threading.Thread(target=run, args=("t1",))
t2 = threading.Thread(target=run, args=("t2",))
t1.start()
t2.start()
--------------------------------------------

2. 自定义线程类

import threading
class MyThread(threading.Thread):
def __init__(self, name):
super(MyThread, self).__init__()
self.name = name
def run(self):
for i in range(3):
print(self.name)
if __name__ == "__main__":
t1 = MyThread("t1")
t2 = MyThread("t2")
t1.start()
t2.start()
|
二、线程的使用
1.守护线程
子线程会随着主线程的结束而结束
t = threading.Thread(target=run, args=("t1",))
t.setDaemon(True) # 把子进程设置为守护线程，必须在start()之前设置
t.start()
2.主线程等待子线程结束
t = threading.Thread(target=run, args=("t1",))
t.setDaemon(True)
t.join() # 设置主线程等待子线程结束
t.start()
3.互斥锁

from threading import Thread,Lock
n = 10
def run():
global n
locker.acquire()
n -= 1
locker.release()
if __name__ == '__main__':
locker = Lock()
t1 = Thread(target=run)
t2 = Thread(target=run)
t1.start()
t2.start()
