Do you need the data to be ordered? If not, just use a dictionary:
d = {'First Name:': '', 'Last Name:': ''}
d['First Name:'] = 'Bob'
d['Last Name:'] = 'Smith'

Dennis is absolutely right. The reason you won't find a method in the
standard libraries for doing this task specifically is because python
aims to by cross-platform. If it were to support a method that worked
in the way you describe specifically for Windows, that would
essentially break python's

The else clause *is* executed when there is no data on which to itera

How about something like:
class Forwards(object):
to_forward = set(['flush', 'read', 'write', 'close'])
def __init__(self, backends):
self.backends = backends
def forwarder(self, methodname)
