1,安装Python,安装ffmpeg,安装terminal(这个微软商店里下载),在terminal里进行操作。(后面会放链接)测试python和pip 使用pip安装 按照提示更新pip 测试ffmpeg 2,注意添加环境变量:给Python和ffmpeg添加环境变量(如果你之前使用annie的话,ffmpeg环境变量已经添加完毕了,添加环境变量的操作请看链接,,annie中cmd的几种使用方...

python 多线程编程之_thread模块 参考书籍:python核心编程 _thread模块除了可以派生线程外,还提供了基本的同步数据结构,又称为锁对象(lock object,也叫原语锁、简单锁、互斥锁、互斥和二进制信号量)。 下面是常用的线程函数: _thread模块的核心函数是start_new_thread()。专门用来派生新的线程。
