I think what you want to do is subclass the file type.
Here's a simple subtype of the file class that has
input from one file and output to another class. It
will act similarly to a file in rU+ mode.
def __init__(self, inputfile, outputfile):
self.inputfile = file(inputfile, 'rU')
self.outputfile = file(outputfile, 'w')
def read(self, *args):
def write(self, *args):
