Python 线程池模块之多线程操作代码

if __name__ == '__main__':
 # 列表推导式
 [pool.submit(fun,i,i) for i in range(20) if True]
 # 单个线程的执行
 task = pool.submit(fun,'Hello','world')
 # 判断任务执行状态
 print(f'task status {task.done()}')
 time.sleep(4)
 print(f'task status {task.done()}')
 # 获取结果的函数是阻塞的，所以他会等线程结束之后才会输出
 print(task.result())

print(task.result())

for future in as_completed(all_task):
 data = future.result()

# 等待线程全部执行完毕
wait(pool.submit(fun,1,2),return_when=ALL_COMPLETED)
print('')
