a quick program to download tv listings

[Erik Lechak]

Hello all,

Is there anyone out there that has written anything in python to
download tv listings (no XML)?

All the tv listing stuff that I can find is way too complex for my
taste (includes XML overkill or is not in python).  I wrote the test
program below and it works.  I am just curious if anyone has a more
robust python implementation before I take the time to add all the
bells and whistles.

Chron is just a class like datetime, but I wrote it to accept just
about every english way of expressing time.  The important thing is to
put the epoch time in the URL.

If anyone is interested in Chron, I can post it or send it to them.

Hope you enjoy the code,
Erik Lechak

import urllib
import re
from pygra.Chron import Chron

class Show:
    '''
    Just a structure to hold program information
    '''
    def __init__(self):
        name=""
        channel=""
        station=""
        start=""
        end=""

 
def getGrid(timestring):
    shows=[]
    t=Chron(timestring)
    f = urllib.urlopen('http://tv.yahoo.com/grid?lineup=us_DMA560&genres=&dur=&starttime='+str(int(t.epoch))+'&.intl=us')
    data = f.read()
    data=[d.strip('\n') for d in data]
    data="".join(data)
    data=data.split("</A>")
    for d in data:
        progs = re.findall('<A HRef="\/tvpdb\?d=tvp&id=(.*)',d)
        for s in progs:
            m= re.search('(\d*)&cf.*channels=us_([^&]*).*&chname=([^\+]*)\+(\d+)&progutn=(\d*)&.*>(.*)',s)
            show=Show()
            show.name=m.group(6)
            show.start=m.group(5)
            show.channel=int(m.group(4))
            show.station=m.group(3)
            shows.append(show)
    return shows
 

shows =getGrid('now')

for s in [s for s in shows if s.channel==17]:
        print s.name
