Python获取央视节目单的实现代码

本文实例讲述了python/' target='_blank'>python获取央视节目单的方法。分享给大家供大家参考。具体如下：

#! /usr/bin/Python # -*- coding: utf-8 -*- import urllib,re,unicodedata,string,sys from time import strftime,localtime channel={"1":"CCTV-1","2":"CCTV-2","3":"CCTV-3","4":"CCTV-4亚洲",   "5":"CCTV-4欧洲","6":"CCTV-4美洲","7":"CCTV-5","8":"CCTV-6",   "9":"CCTV-7","10":"CCTV-8","11":"CCTV-9","12":"CCTV-10",   "13":"CCTV-11","14":"CCTV-12","15":"CCTV新闻","16":"CCTV少儿",   "17":"CCTV音乐","18":"CCTV_E","19":"CCTV-F","20":"CCTV-高清"} if __name__=="__main__":   print "@@"   print "@@ 你可以在命令行后输入数字(1-20)来选择频道 "   print "@@ 通过在命令行后键入help获取频道列表"   print "@@"   if len(sys.argv)==1:     Select="8"   else:     if sys.argv[1]=="help":       for i in range(len(channel)):         print "%3d : %11s" % (i+1, channel["%s" % (i+1)]),         if(i%4 == 3):           print ""       sys.exit(0)     if string.atoi(sys.argv[1])>20 or string.atoi(sys.argv[1])<=0:       print "Out of Range.
