python开启多线程

在Python中,可以通过使用线程库中的Thread类来开启多线程。可以使用以下代码来开启多线程:
```
from threading import Thread
def task():
# 子线程的任务逻辑
print('子线程开始')
# 执行任务
print('子线程结束')
t = Thread(target=task)
t.start()
```
这段代码创建了一个名为t的线程对象,并通过target参数指定了要在线程中执行的任务。然后使用start()方法启动线程。这样就可以开启一个新的线程来执行task函数中的任务。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
