实际应用，合并libsvm所需要格式的两个txt特征值
方法1：
#coding=utf-8
import numpy as np
import os
cwd = os.getcwd()
txtFile1 = cwd + '/first.txt'
txtFile2 = cwd + '/second.txt'
mergeFile2 = cwd + '/mergeTXT.txt'
f = file(mergeFile2, 'a+')
for (index1, line1) in enumerate(open(txtFile1)):
# print index1, line1
for (index2, line2) in enumerate(open(txtFile2)):
if index1 == index2:
newline = line1 + line2 + '\n'
f.write(newline)
f.close()
方法2：
first=[]
second=[]
f=open('mergeTXT.txt','w')
with open('first.txt', 'r') as f1:
for line in f1:
line=line.strip()
first.append(line)
with open('second.txt', 'r') as f2:
for line2 in f2:
line2=line2.strip()
second.append(line2)
for i in range(0,399):
result=first[i]+'\t'+second[i]+'\n'
f.write(result)
