Including:

- What Python code can I use to find all the network ports that are in 
use on a server?
- Can I use python to access web (eg.yahoo) email account?
- Is there any way to find the mount point of a filesystem given the 
path to a file within the file system?
- How can I create a wxBitmap image from a Python Imaging Library (PIL) 
image?

to figure out what ports are used on a server you could use netstat -a 
-n

import os 
popen("netstat -a -n")

For web mail accounts that have POP access, such as Yahoo, check out
the 'poplib' standard library module:

I didn't find anything already extant, so here's this:

def mountpoint(s):
    import os
    if (os.path.ismount(s) or len(s)==0): return s
    else: return mountpoint(os.path.split(s)[0])

def testit():
    print mountpoint("/home/john/scheme/cmucl")
    print mountpoint("/usr/local")
    print mountpoint("/lib/")
    print mountpoint("lib")

Here's some sample code:
def PilImgToWxBmp(pilImg):
  wxImg = wxEmptyImage(pilImg.size[0],pilImg.size[1])
  wxImg.SetData(pilImg.tostring())
  bmp = wxImg.ConvertToBitmap()
  return bmp

import string

if string.lower("FOO") == string.lower("Foo"):
   <do something useful>
