I think you should be able to use my or goodwolf's solution with the
subprocess module. Something like this (untested):

[code]
class TeeFile(object):
    def __init__(self,*files):
        self.files = files
    def write(self,txt):
        for fp in self.files:
            fp.write(txt)

if __name__ == "__main__":
    import sys
    from subprocess import Popen

    command = "whatever you want to run"
    outf = file("log.out","w")
    errf = file("log.err","w")
    allf = file("log.txt","w")
    Popen(
        command,
        stdout = TeeFile(sys.__stdout__,outf,allf),
        stderr = TeeFile(sys.__stderr__,errf,allf)
    )
[/code]
