## _thread – 多线程支持
|
|||
|
|
|
|||
|
|
`_thread` 模块提供了用于处理多线程的基本方法——多个控制线程共享它们的全局数据空间。为了实现同步，提供了简单的锁（也称为互斥锁或二进制信号量）。
|
|||
|
|
|
|||
|
|
### 示例
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
import _thread
|
|||
|
|
import time
|
|||
|
|
def testThread():
|
|||
|
|
while True:
|
|||
|
|
print("Hello from thread")
|
|||
|
|
time.sleep(2)
|
|||
|
|
|
|||
|
|
_thread.start_new_thread(testThread, ())
|
|||
|
|
while True:
|
|||
|
|
pass
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
输出结果（启动新的线程，每隔两秒打印字符）：
|
|||
|
|
|
|||
|
|
Hello from thread
|
|||
|
|
Hello from thread
|
|||
|
|
Hello from thread
|
|||
|
|
Hello from thread
|
|||
|
|
Hello from thread
|
|||
