Process([group[,target[,name[,args[,kwargs]]]),由该类实例化得到的对象, 表示一个子进程中的任务(尚未启动) 强调:1.需要使用关键字的方式来指定参数2.args指定的为传给target函数的位置参数,是一个元组形式,必须有逗号 1. 2. 3. 4. 5.

multiprocessing.Process模块 process模块是⼀个创建进程的模块，借助这个模块，就可以完成进程的创建。process模块介绍 Process([group [, target [, name [, args [, kwargs]]])，由该类实例化得到的对象，表⽰⼀个⼦进程中的任务（尚未启动）强调：1. 需要使⽤关键字的⽅式来指定参数 2. args指定...
The 'args' parameter of the 'Process' class allows passing arguments to the target function. In this example, the string "Avalon" is passed to the 'greet' function, which is executed by the process. Using a Pool of Workers: A 'Pool' allows you to manage multiple worker processes and di...
