Python获取央视节目单的实现代码

本文实例讲述了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. Please Select 1-20." 
          sys.exit(0) 
        else: 
          Select=sys.argv[1] 
      print '正在获取节目单，请稍后...' 
      date=strftime('%Y%m%d',localtime()) 
      response = urllib.urlopen("http://tv.cctv.com/soushi/28/0"+Select+"/"+date+".shtml") 
      Result=response.read() 
      #list=re.findall(r"<div class='tlb_right'><div class='l'>(.+?)<script",Result,re.S) 
      list=re.findall(r"上午节目(.+?)<script",Result,re.S)

      morning=[] 
      afternoon=[] 
      listnum=0 
      for i in range(len(list2)): 
        i=re.sub('<.+?>','',list2[i]) 
        if string.atoi(i[:2])>=12: #将上午的节目于下午的节目分开 
          afternoon.append(i) 
        else: 
          morning.append(i) 
      if len(morning)>len(afternoon): 
        listnum=len(morning) 
      else: 
        listnum=len(afternoon) 
      print "-"*80, 
      print " "*13+"上午节目"+" "*26+"下午节目" 
      print " "*14+"========"+" "*26+"========" 
      for i in range(listnum): 
        if(i<len(morning)): 
          print "%-4s %-29s" %(morning[i][:5],morning[i][5:]), 
        else:

        if(i<len(afternoon)):
