好的,下面是注释版的代码:
使用创建线程的方式:
```python
import threading
# 定义一个继承自 threading.Thread 的子类 MyThread
class MyThread(threading.Thread):
def __init__(self, num):
# 初始化函数,保存线程编号
threading.Thread.__init__(self)
self.num = num
def run(self):
# 线程执行函数,输出线程开始和结束的日志
print('Thread %d started' % self.num)
# do some work here...
print('Thread %d finished' % self.num)
threads = []
for i in range(5):
# 创建 MyThread 对象,并启动线程
t = MyThread(i)
threads.append(t)
t.start()
# 等待所有线程执行完毕
for t in threads:
t.join()
print('All threads finished')
```
使用集成线程的方式:
```python
import _thread as thread
import time
def worker(num):
# 线程执行函数,输出线程开始和结束的日志
print('Thread %d started' % num)
# do some work here...
print('Thread %d finished' % num)
threads = []
for i in range(5):
# 启动新线程,并保存线程标识符
t = (i,)
thread.start_new_thread(worker, t)
threads.append(t)
# 循环等待所有线程执行完毕
while threads:
time.sleep(0.1)
for t in threads:
# 检查每个线程标识符是否还存在,如果不存在,则说明该线程已经执行完毕,从列表中移除
if not thread._count().__contains__(t):
threads.remove(t)
print('All threads finished')
```
上面的注释中,对每个函数和关键步骤都进行了详细的说明,希望能够帮助你更好地理解代码的实现过程。
