原始数据划分为train.dat和test.dat
应用背景开始是做movielense的数据，可以把原始数据任意划分为train.dat和test.dat，主要是为了做验证实验。非常简单明了，适合初学者看看，如果不喜欢，请轻喷。关键技术# -*- coding: cp936 -*-
from sklearn import cross_validation
c = []
filename = r"Raw.data" #原始数据
out_train = open(r"train.txt","w") #训练集
out_test = open(r"test.txt","w") #测试集
for line in open(filename):
items = line.strip().split(",")
c.append(items)
c_train,c_test = cross_validation.train_test_split(c,test_size=0.1)#size =你需要的比例
for i in c_train:
out_train.write(",".join(i)+"
")
for i in c_test:
out_test.write(",".join(i)+"
")

进程调度是处理机管理的核心内容。本实验要求用C语言编写和调试一个简单的进程调度程序。通过本实验可以加深理解有关进程控制块、进程队列的概念，并体会和了解优先数和时间片轮转调度算法的具体实施办法-scheduling process management processor is the core content. The experiment called for using the C language and debug a simple process scheduler. Through this experiment can deepen our understanding of the process control block, the concept of the process of formation and to experience and understand a few priorities and time-Cycle Scheduling Algorithm of concrete measures for implementation
