from multiprocessing import cpu_count 这行代码的作用就是从multiprocessing模块中导入cpu_count函数,以便在后续的代码中使用它。 调用cpu_count函数,获取当前系统的CPU核心数量: 一旦cpu_count函数被导入,就可以通过调用它来获取当前系统的CPU核心数量。这个信息对于并行编程和性能优化来说非常有用,因为它可以帮助开发...

multiprocessing模块可以让程序员在给定的机器上充分地利用CPU。在multiprocessing中,通过创建Process对象生成进程,然后调用start()方法。 创建多进程语法如下: multiprocessing.Process ( function, args[, kwargs] ) 参数说明: function - 函数名 args - 传递给函数的参数,必须是个tuple类型 kwargs - 可选参数 i...
