Help with __name__ == '__main__'

[Manuel]

Hi, Thanks a lot for the help from Skip Montanaro and Andreas Jung!

But now a new question. This is the complete code and I am not able to call
the function so, that it only prints out e.g. the gethost list. How can I
handle this in __name__ == '__main__'! Or is there another possibility to
handle this more elegant or simpler? Thanks for help and hints!
The function call should be in this type:
python filelist.py serverlist.txt
and optional:  python filelist.py serverlist.txt gethost
or  python filelist.py serverlist.txt getprotocol getpath

Thanks for help and hints!


filelist.py
import sys, string, urlparse

class ListFile:

  def __init__(self, filename):
      self.file = open(filename, 'r')



  def __getitem__(self, i):
      line = self.file.readline()
      if line:
          return line
      else:
          raise IndexError

  def __getattr__(self, name):
      return getattr(self.file, name)

  def getall(self):
      for line in self.file:
          parseurl = urlparse.urlparse(line)
          getprotocol = parseurl[0]
          gethost = parseurl[1]
          getpath = parseurl[2]
          print getprotocol, gethost, getpath,

  def getprotocol(self):
      for line in self.file:
          parseurl = urlparse.urlparse(line)
          getprotocol = parseurl[0]
          print getprotocol

  def gethost(self):
      for line in self.file:
          parseurl = urlparse.urlparse(line)
          gethost = parseurl[1]
          print gethost

  def getpath(self):
      for line in self.file:
          parseurl = urlparse.urlparse(line)
          getpath = parseurl[2]
          print getpath,

if __name__ == '__main__':
  line = ListFile(sys.argv[1])
  line.getall()
  line.getall()
  line.getprotocol()
  line.gethost()
  line.getpath()
