在没有控制台的情况下使用Popen在pythonw中运行进程

从这里：

import subprocessdef launchWithoutConsole(command, args):    """Launches 'command' windowless and waits until finished"""    startupinfo = subprocess.STARTUPINFO()    startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW    return subprocess.Popen([command] + args, startupinfo=startupinfo).wait()if __name__ == "__main__":    # test with "pythonw.exe"    launchWithoutConsole("d:\bin\gzip.exe", ["-d", "myfile.gz"])

请注意，有时抑制控制台会使子流程调用失败，并显示“错误6：无效的句柄”。一种快速修复是重定向
