It is a very useful technique for time-saving and improving the performance of an application. Multithreading allows the programmer to divide applicationtasksinto sub-tasks and simultaneously run them in a program. It allows threads to communicate and share resources such as files, data, and memory...

目前python 提供了几种多线程实现方式 thread,threading,multithreading ,其中thread模块比较底层,而threading模块是对thread做了一些包装,可以更加方便的被使用。2.7版本之前python对线程的支 持还不够完善,不能利用多核CPU,但是2.7版本的python中已经考虑改进这点,出现了multithreading 模块。threading模块里面主要是对一些线...
2.7版本之前python对线程的支持还不够完善,不能利用多核CPU,但是2.7版本的python中已经考虑改进这点,出现了multithreading 模块。threading模块里面主要是对一些线程的操作对象化,创建Thread的class。一般来说,使用线程有两种模式: A 创建线程要执行的函数,把这个函数传递进Thread对象里,让它来执行; B 继承Thread类,创建...
