這篇文章主要介紹了Python獲取央視節(jié)目單的實現(xiàn)代碼,涉及Python頁面采集的相關技巧,具有一定參考借鑒價值,需要的朋友可以參考下

本文實例講述了Python獲取央視節(jié)目單的方法。分享給大家供大家參考。具體如下：

#! /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亞洲", 
  "5":"CCTV-4歐洲","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新聞","16":"CCTV少兒", 
  "17":"CCTV音樂","18":"CCTV_E","19":"CCTV-F","20":"CCTV-高清"} 
if __name__=="__main__": 
  print "@@" 
  print "@@ 你可以在命令行后輸入數(shù)字(1-20)來選擇頻道 " 
  print "@@ 通過在命令行后鍵入help獲取頻道列表" 
  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 '正在獲取節(jié)目單，請稍后...' 
  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"上午節(jié)目(.+?)<script",Result,re.S) 
  list2=re.findall(r"<li>(.+?)</li>",list[0],re.S) 
  morning=[] 
  afternoon=[] 
  listnum=0 
  for i in range(len(list2)): 
    i=re.sub('<.+?>','',list2[i]) 
    if string.atoi(i[:2])>=12: #將上午的節(jié)目于下午的節(jié)目分開 
      afternoon.append(i) 
    else: 
      morning.append(i) 
  if len(morning)>len(afternoon): 
    listnum=len(morning) 
  else: 
    listnum=len(afternoon) 
  print "-"*80, 
  print " "*13+"上午節(jié)目"+" "*26+"下午節(jié)目" 
  print " "*14+"========"+" "*26+"========" 
  for i in range(listnum): 
    if(i<len(morning)): 
      print "%-4s %-29s" %(morning[i][:5],morning[i][5:]), 
    else: 
      print " "*35, 
    if(i<len(afternoon)): 
      print "%-4s %-30s" %(afternoon[i][:5],afternoon[i][5:]) 
    else: 
      print " "*37 
  print "-"*80, 
  print " "*24,strftime("%Y年%m月%d日"), 
  print "%s 節(jié)目單" %channel[Select]
