我想从message：response中提取名词，并在控制台中显示或打印它们，如何做到这一点？我厌倦了ntlk和textbob之类的东西，但我不知道如何正确实现它。我甚至问了github copoilet，但它只是随机显示，不工作。我有一个任务，涉及从一个名为message的变量中提取名词：response.我想在控制台中显示提取的名词或将它们打印在屏幕上。如何使用Python完成此任务？我试过使用一些库，比如NLTK和TextBlob，但我不确定如何正确使用它们。我也向GitHub Copilot寻求帮助，但是它没有生成任何有用的代码。2它只是显示了一些不起作用的随机输出。3有人能帮我解决这个问题吗？
