python 竖排文本

新建目录train，并将目录data和data1复制到train下

python test data/,data1/

目录data和data1中包含很多文件，文件中内容都是以空格分隔，将所有文件内容都以空格为分隔符，竖向排列覆盖到train下相应目录中

import sys
import os

def main(argv):
    arg=sys.argv[]
    print arg
    data_set_list = []
    for data_set_num, data_dir in enumerate(arg.split(","), ):
        command="ls -l %s |awk 'NR==2,NR==0 {print $NF}'" % (data_dir)
        fp=os.popen(command, "r")
        ret=fp.readlines()
        for data_name in ret:
            data_path=data_dir+data_name[:-]
            data_set_list.append(data_path)
    print("data_set_list:",data_set_list)

    for data_index, data_set_name in enumerate(data_set_list):
        f = open(data_set_name,'r')
        result=f.read()
        f.close()

            o.write(i)
            o.write('\n')
        o.close
