rola_songbird.py

Based on the script published by gnuget rola-banshee.py this is a little hack to work with songbird 1.1.1 using the dbus add-on, with 1.1.2 don’t work because the add-on didn’t work with the new version

download links with python

Lately (about 3 days ago) I’ve started learning python, and this is a little script I made for download all the links of a page, you give it the html file (it have to be a local html, it can’t use an url, so save the page and use it) and the extension of the files you want to download, it use wget, so I know there are hundreds of script or software that can do this an maybe so much better but I want to do it just for didactic purpose, so here it is:

#!/usr/bin/env python
import sys
import os

#get two args:
# file name to search in
# extension of link to download

#use ./filename file.html extension_to_search

file = open(sys.argv[1], 'r')
ext = str(sys.argv[2])

extLength = len(ext)
lineas = file.readlines()

for line in lineas:
  if  line.find('href="') != -1:
    hrefpos = line.find('href="')
    #+6 to add the length of href="
    if line[hrefpos+6:].find(ext) != -1:
      lastpos = line[hrefpos+6:].find(ext)
      #extLength added so the string contains the extension
      dfile = line[hrefpos+6:][:lastpos+extLength]
      os.system("wget -c " + dfile)

Cheers
