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-*-
importurllib,re,unicodedata,string,sys
fromtimeimportstrftime,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"@@"
iflen(sys.argv)==1:
Select="8"
else:
ifsys.argv[1]=="help":
foriinrange(len(channel)):
print"%3d:%11s"%(i+1,channel["%s"%(i+1)]),
if(i%4==3):
print""
sys.exit(0)
ifstring.atoi(sys.argv[1])>20orstring.atoi(sys.argv[1])<=0:
print"OutofRange.PleaseSelect1-20."
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"<divclass='tlb_right'><divclass='l'>(.+?)<script",Result,re.S)
list=re.findall(r"上午节目(.+?)<script",Result,re.S)
list2=re.findall(r"<li>(.+?)</li>",list[0],re.S)
morning=[]
afternoon=[]
listnum=0
foriinrange(len(list2)):
i=re.sub('<.+?>','',list2[i])
ifstring.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)
iflen(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+"========"
foriinrange(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节目单"%channel[Select]
