需求：  多进程，加快程序运行。#示例1from multiprocessing import Pool, TimeoutErrorfrom multiprocessing import cpu_countimport timeimport osdef f(x): time.sleep(1) return [x*x, x*x], x,'success'if __name__ == '__main__': # start 4 worker processes

需求：  在不同的进程中分别启动flask服务，或将其部署到不同的端口号上。# 导入flask类import flaskimport multiprocessing as mpimport time# 创建Flask实例，接收参数__name__表示当前文件名，默认会自动指定静态文件staticapp1 = flask.Flask(__name__)app2 = flask.Flask(__name__)app3 = flask.Flask(__name__)# app1@app1
