我試圖每 10 秒重新運行一次我的 python 腳本。我已經嘗試了 time.sleep 函數的各種方法，但似乎沒有任何效果。我嘗試過 time.sleep 的不同變體： def job() # scriptif __name__ == '__main__': while True: job() time.sleep(10)但沒有找到正確的地點/方式來實施它。我不想重新運行函數，而是完整的代碼。這是我嘗試重新運行的腳本：import...def main(): # parse the command line arguments args = ConfigArgumentParser(description=__doc__).parse_args() if _debug: _log.debug("initialization") if _debug: _log.debug(" - args: %r", args) # make a device object this_device = LocalDeviceObject( objectName=args.ini.objectname, objectIdentifier=('device', int(args.ini.objectidentifier)), maxApduLengthAccepted=int(args.ini.maxapdulengthaccepted), segmentationSupported=args.ini.segmentationsupported, vendorIdentifier=int(args.ini.vendoridentifier), ) # make a sample application this_application = BIPSimpleApplication(this_device, args.ini.address) # make some random input objects for i in range(1, RANDOM_OBJECT_COUNT + 1): ravo = RandomAnalogValueObject( objectIdentifier=('analogValue', i), objectName='Temp%d' % (i,), ) this_application.add_object(ravo) # make sure they are all there _log.debug(" - object list: %r", this_device.objectList) _log.debug("running") run() _log.debug("fini")if __name__ == "__main__": main()

如果您需要運行整個過程（甚至是引導代碼），您可以使用 shell 腳本來完成。
但這不會刷新環境變量。
#!/usr/bin/env bash
while true; do?
? sleep 10
? python script.py
done
如果您需要刷新環境變量（由于 RANDOM_OBJECTS，您似乎需要它），請添加eval "$(exec /usr/bin/env -i "${SHELL}" -l -c "export")"到其中。

你能做的就是在 10 秒后重新啟動整個腳本。
應用于您的代碼，它看起來像這樣：
