## _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
