python 类如何继承线程

Python 中的 `threading` 模块提供了 `Thread` 类,用于创建新线程。如果你想要创建一个类去继承这个 `Thread` 类,以便自定义线程的行为,你可以按照以下步骤操作:
1. 首先,导入 `threading` 模块:
```python
import threading
```
2. 然后,定义一个新的类,并继承自 `threading.Thread`。在这个类中,你可以覆盖或添加 `__init__()`、`run()` 等方法,`run()` 方法通常是你希望线程执行的具体工作部分:
```python
class CustomThread(threading.Thread):
def __init__(self, target_function, *args, **kwargs):
super().__init__(*args, **kwargs) # 调用父类的构造函数
self.target_function = target_function # 存储待执行的目标函数
def run(self):
self.target_function() # 在这里执行目标函数
```
3. 创建并启动自定义线程实例:
```python
def my_task():
print("Custom thread is running.")
custom_thread = CustomThread(my_task)
custom_thread.start()
```
在这个例子中,`my_task` 就是 `run()` 方法中实际执行的任务。你可以在 `run()` 方法里完成任何需要执行的代码。
