multiprocessing是python的多进程库,multiprocessing.dummy则是多线程的版本,使用都一样。 其中都有pool池的概念,进程池/线程池有共同的方法,其中方法对比如下 : There are four choices to mapping jobs to process. Here are the differences: Multi-argsConcurrenceBlockingOrdered-resultsmapnoyesyesyesapplyyesnoyesno...
思路2:使用 function.partialPassing multiple parameters to pool.map() function in Python。这个不灵活的方法固定了其他参数,且需要导入 Python 的内置库,我不推荐 代码语言:javascript 代码运行次数:0 运行 AI代码解释 importtime deffunc2(args):# multipleparameters(arguments)# x,y=args x=args[0]# write...
(Python multiprocessing Process class) Python multiprocessing Process class is an abstraction that sets up another Python process, provides it to run code and a way for the parent application to control execution. Python多重处理Process类是一种抽象,它建立了另一个Python进程,为它提供了运行代码的方式,...
