You can use this:

win32api.ShellExecute(0,"open",filename,None,workingdir,1) for open
win32api.ShellExecute(0,"edit",filename,None,workingdir,1) for edit

Where filename is an absolute path to the file, and workingdir is best
set to the directory of the file, None refers to any commandline
arguments, and finally the last 1 makes the application visible as a
normal window.

see http://docs.activestate.com/activepython/2.4/pywin32/win32api__ShellExecute_meth.html
and http://support.microsoft.com/kb/238245

However, I just found out that not every file has an edit action
causing the shellexecute to fail.
So you need to fall back to open

try:
    try:
        win32api.ShellExecute(0,"edit",filename,None,workingdir,1)
    except win32api.error:
        # Fall back to open
        win32api.ShellExecute(0,"open",filename,None,workingdir,1)
except win32api.error:
    print "Can't start %s" % filename

Don't know if there is a way to find out when edit is not there.

Cheers,
