>From within python you colud do something like:

class PushFile:
    def __init__(self, fp):
        self.fp = fp
    def readline(self):
        if self.pushback:
            return self.pushback.pop()
        else:
            return self.fp.readline()
    def push(self, line):
        self.pushback.append(line)

and replace the file you're reading from with PushFile.  This can be handy for
automatically testing interactive programs.

If you want to control an external program's keyboard input, see the expect
module.
