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)+" ")

扫描子文件夹的示例，对某些文件夹操作，查找等特别有用。看似简单但不知道，对有些操作就会特头痛。 //复杂的程序都是由不起眼的东东拼凑起来的-scan subfolders example, the right to operate certain folder, find out as particularly useful. Seemingly simple, but I do not know, for some special operation will be a headache.// Complex procedures are unremarkable pieced together Wanton
