Use the popen2 function from the os module as in the following example:

        import os
        import string

        # make sure to call ocatve with the "quiet" flag
        [pwrite, pread] = os.popen2("octave -q","w")

        pwrite.write("x = [1,2,3];\n")
        pwrite.write("printf('%f\\n', sum(x));\n")

        # always flush the output to avoid deadlocks
        pwrite.flush()
        result = pread.readline()
        print ("Sum = %f" % string.atof(result))

        pwrite.close()
        pread.close()
