Write a small script to download teahour audio using python

preface

Recently, in my spare time, I saw a small station I had been paying attention to before, http:// teahour.fm /,1. I wanted to listen to all the audio here once, but suddenly I have been doing nothing for two years. A little sad, so I wrote a script, grabbed the audio download link, after downloading down 1 must listen carefully.

Time is short, and debugging is also so 10 minutes, the script may be some bad, you can point out the message.

teahour.py

 #!/usr/bin/env python
 #coding: utf-8
 
 import sys
 import requests
 from BeautifulSoup import BeautifulSoup
 
 reload(sys)
 sys.setdefaultencoding( "utf-8" )
 
 def parse_index():
  l = []
  r = requests.get("http://teahour.fm/")
  text = r.text
  html = BeautifulSoup(text)
  a = html.findAll("ul")[-3].findAll("a")
  for item in a:
   url = "".join(["http://teahour.fm",item.attrs[0][1]])
   title = item.text
   title = title.strip("#")
   l.append((title,url))
  return l
 
 def write(lines):
  with open("teahour.sh","a") as fh:
   fh.writelines(lines)
 
 def parse_sub(t):
  title,url = t
  r = requests.get(url)
  text = r.text
  html = BeautifulSoup(text)
  audio_url = html.find("audio").attrs[-1][-1]
  ext = audio_url.split(".")[-1]
  line = "wget '%s' -SO '%s.%s'\n" % (audio_url,title,ext)
  #print line
  return line
 
 def main():
  lines = []
  l = parse_index()
  for t in l:
   line = parse_sub(t)
   lines.append(line)
  write(lines)
 
 if __name__ == "__main__":
  main()
